Matenals handling systems are an integrating component of a manufacturing
system and as such rnust be considered within an integrated approach to manufacturing
systems design.
This work proposes to integrate the operation allocation and the
materials handling system selection problems in a flexible manufactwing system by
extending the operation allocation model to include some aspects of materials handling
system design. The objective of the operation allocation model is to select a group of
machines where the operations of the part types wiII be perforrned and then to assign
those operations to the selected machines. The operation allocation model interfaces with
the materials handling system selection model by providing input data in the f o m of the
manufacturing operations to be perfomed at each machining center. The selection of the
materials handling system is centered on the matching of the parts visiting a machining
center to perform a manufacturing operation and the abiiities of the handling equipment
to perfom the required materials handling functions of those part types. The objective is
to select an optimal group of materials handling equipment to be assigned to a cell. A
compiiter program was developed to greatly automate the process of solving the models.
This allows the program to be used as a rapid rnodeling tool.

The environment under which manufacturing organizations operate is changing
rapidly.
The emerging post-industnal environment is charactenzed by fierce global
competition, rapid market changes, shorter product life cycles and advances in both
manu facturing and information tec hnology (Vonderembse et al ., 1997).
These
environmental changes have a direct effect on the design of manufacturing systems
spawning significant changes to that design.
The widening of competition to a global realm, made increasingly possible by the
emergence of various international trade agreements and facilitated by the recent
advances in information technologies, places an added demand on the manufacturing
systems to produce "agile" products. These products must be continuously produced to
closer tolerances, with higher reliability and fiom an expanding variety of matenais.
The shorter product life cycles and rapid market changes lead to a proIiferation in
the number and variety of products that must be produced within a rnanufacturing
facility. The emphasis has shifted to producing this large array of new and improved
products in smaller volumes as rapidly and economically as possible.
Other changes include the recognition of the cost of matenals, materials handling
and energy as significant cornponents of the total manufacturing cost. This is especially
true for materials handling. Tompkins and White (1984) estimated that between 20-50%
of the total operating cost in manufacturing can be attributed to the various materials
handling functions.
Advances in manufacturing and information technology make these trends
seemingly feasible to accommodate. Technological advances in CAD/CAM/CiM and
flexible manufacturing systems or cells cm, at least in theory, provide the flexibility and
efficiency required to successfÙlly cope with the changes outlined above. However, in
many cases, this has not proved to be true, or at least not to the extent that one would
expect. While these advanced technologies have been successfully exploited for specific
tasks, often the required system-wide benefits have not been achieved.
A manufacturing system is a complex of smaller interacting subsystems. The
changes and trends discussed previously affect these subsystems and therefore the
manufacturing capability of the whole system. Due to the relationships among these
subsystems, it is necessary to consider the manufacturing system fiom an integrated
standpoint.
The focus on integration guarantees that critical information exchange
between the subsystems is considered.
This is of paramount importance to a
manufacturing system that must produce a large variety of low-medium volume products
in a reliable. time efficient and resource efficient manner.
1.1.
Motivation for the Proposed Research
htegration should be the focus of a post-industrial manufacturing fim. As such,
the manufacturing system must be viewed from a holistic perspective as an integrated
whole. This "whole" is composed of a number of interacting and integrated subsystems.
Each subsystem has certain objectives that it must meet; however, its operations must be
fine-tuned to optimize the "whole".
Flexible manufacturing systems or cells have the potential to provide the
flexibility and efficiency required by the post-industrial firm. This has been widely
recognized and has been the motivating factor behind a large volume of research in this
area.
This is to be expected since flexible manufacturing systems require carefûi
planning to ensure that resources arc not underutilized, flexibility is maximized, and setup costs are minimized. One of the principal tasks to be performed is the optimal
selection of machines and the allocation of part operations to the selected machines. This
task is usually performed while tryng to meet a number of objectives. These include
minimization of operation, machine set-up and materials handling costs, minimization of
total processing times, maximization of machine utilization, etc.
The materials handIing system can be thought of as the basic integrator of a
manufacturing system. AAer all, the materials handling system connects and traverses al1
departments and cost centers. Because of its integrating nature, al1 complexity inherent
in a manufacturing problem is passed on to the matenals handling system (Noble and
Tanchoco, 1994).
The high complexity of a materials handling system makes the
selection of an appropriate system a non-trivial problem.
Even for a modest size
manufacturing system, the design details increase rapidly. There is a large variety of
standard and specialty equipment, each with different characteristics that can be dificult
to quantify for inclusion in a model. Funher, there can be multiple objectives to consider
for any specific situation. Computationally, the size of the problem grows very rapidly as
each piece of equipment c m perform a number of operations at a machining center or
between machining centers. Finally, it c m be difficdt to estimate some parameters such
as cost and time before the system is in operation.
Despite the complexity involved in selecting a matenals handling system, it is
extremely important that the problem be carefiilly considered. The magnitude of the cost
impact of materials handling justifies such an effort. Past research on the design and
selection of a materials handling system has focused primarily on the optimization of
materials handling equipment. More recent work has considered the materials handling
systern as a "whole", rather than just individual elements of that system. This is of great
importance since the objective is to optimize the whole.
At the center of a materials handling system is the material itself. Therefore, it is
necessary to start the design cycle by considering the material, its transformation
processes and the resultant products.
The logistics design needs to be undertaken
concurrently with the materials handling system design. Traditionally this has not been
the case. Rather, it is only considered once the products have been engineered and bills
of materials have been produced. By that time, considerable product Iead time has been
lost.
As a resuk of the r a s o n s described above, it is proposed that an integrated
approach to manufacturing system design be developed. More specifically, it is proposed
that the machine selection and operation allocation problem and the materials handling
system selection problem be simultaneously considered to generate a "reasonably
optimal" choice of design features.
1.2.
Organization of the Proposal
The report is divided into eight chapters. This first chapter is an introduction
where some background on the current problems and the motivation for this work is
explained. Chapter 2 presents a literature survey of previous research work on the
operation allocation and materials handling system selection problems. The research
objectives of this work are further defined at the end of that chapter. The operation
allocation and materials handling system selection models are then developed and
presented in Chapter 3. Chapter 4 presents a case study that is solved with the use of the
developed models and the solution to the case study is briefly discussed. In Chapter 5,
the sensitivity analysis of various rating factors used in the materials handling system
selection mode1 is presented. The sixth chapter presents the Solver program that was
developed to sirnplify the solution process to both problems. Chapter 7 discusses the
work presented and offers some ideas for further development of the models. Lastly,
Chapter 8 finalizes with concluding remarks about this research work.
The literature survey is divided into two sections.
The first section reviews
selected literature for the operation allocation problem. The second section reviews the
literature for the materials handling system selection problem.
2. i.
Operation Allocation fiterature
The operation allocation problem has received considerable attention fiom
researchers in the p s t . Several approaches have been proposed to solve the problem.
For the survey of this work, only the mathematical programming approaches are
reviewed. The emphasis is placed on those models that were developed primarily for
flexible manufactuRng systems.
Stecke (1 983) formulated the loading problem in a flexible manufacturing system
as a nonlinear 0-1 mixed integer program. Because the best loading procedure is probiem
dependent, Stecke proposes six different formulations corresponding to six different
loading objectives. These are:
1. Balance the assigned machine processing times.
2. Minimize the number of movements fiom machine to machine.
3. Balance the workload per machine for a system of groups of pooled machines of
equal sizes.
4.
Unbalance the workload per machine for a system of groups of pooled machines
of unequal sizes.
5. Fil1 the tool magazines as densely as possible.
6 . Maximize the sum of operation pnorities.
The formulations are solved by varîous linearization methods.
A branch and bound algorithm was then developed by Berrada and Stecke (1986)
to solve the loading problem more expediently than by means of the linearized
formutations proposed earlier.
However, in this paper, the only loading objective
considered was that o f balancing the workload on al1 machines.
rninimizing the workload of the bottleneck machine.
This is done by
A sequence o f sub-problems is
defined and each sub-problem is solved by a branch and bound procedure.
The
procedure first solves a simple, relaxed assignment problem, next checks for feasibility
and then modifies the assignment to correct the violated constraints.
Lashkari et al. (1987) extended the formulation of the operation allocation
problem to include the planning aspects of refixturing and limited tool availability. The
problem is fomulated as a non-Iinear 0-1 integer programming formulation with two
objective functions. The objective functions consist o f minimization of transport load
and minimization of refixturing activities.
Wilson (1989) proposed an alternative formulation to the one proposed by
Lashkari et al. (1 987). The planning aspects of refixturing and limited tool availability
were also considered.
The alternative formulation avoids the non-linearities of the
previous approach and instead proposes an integer programming formulation. Only the
problem of minimization of transport Ioad is formulated.
Damodaran et al. (1992) presented a mathematical mode1 for the operation
allocation problem in multi-machine and multiple ce11 environments. The mixed integer
linea. model considers the trade-off between refixturïng and materials handling. The
authors argue that this trade-off influences operation allocation. The objective function
minimizes the refixturing and materials handling costs as well as the processing costs.
Taboun and Ulger (1992) developed a muIti-objective modeling o f operation
allocation in flexible manufacturing systems. The 0-1 integer prograrnming formulation
considers multiple objectives such as the minimization of processing, handling, tool setup, fixturinglrefixturing and penalty costs of under-utilization and over-loading of
machining centers.
Ribeiro and Pradin ( 1993) presented a methodoIogy for cellular manu facturing
design that consisted of two stages. In the first stage, the job shop machines are selected
and parts are assigned to those machines. In the second stage, the operation allocation to
seIected machines is realized with the intent of minimizing inter-ce11 moves. The second
phase is developed so that the operator can iteratively repeat it until a certain level of
inter cell moves is achieved.
Atmani et al. (1995) developed a mathematical prograrnming approach to joint
ce11 formation and operation allocation in cellular manufacturing. The mode1 introduced
was a 0-1 integer program that simultaneously considered the ce11 formation and
operation allocation problems while minimizing the sum o f the operation costs,
refixturing costs and transportation costs.
Atmani (1995) proposed a flexible planning mode1 for flexible manufactunng
systems with setup cost consideration. The 0-1 integer prograrnming mode1 rninimizes
the joint operation, materials handling and setup costs. This model was applicable to a
single cell.
Atmani and Lashkari (1998) presented a linear, 0-1 integer programming model
of the machine tool assignrnent and operation allocation in a flexible manufacturing
system.
An optimal plan is obtained by minimizing the total costs of operations,
materials handling (transportation) and machine set-ups.
Guerrero et al. (1999) presented a mixed integer linear programming model of
machine loading and part type selection in flexible manufacturing systems. The model
considers the existence of alternative routes for each part type.
The objective is to
balance the machine workloads.
2.1.
Materials Handling System Selection Literature
The materials handling system selection problem has also received considerable
attention from researchers. Many di fferent approaches have been proposed in past and
recent literature.
C h u et al. (1995) as well as Kim and Eom (1997) have proposed expert based
system approaches. A closely related approach is that of knowledge based solutions.
Some work in this area has been conducted by Matson et al. (1990), and Welgama and
Gibson (1 995). Another popular approach is simulation. Some researchers that have
worked in this area include Nadoli and Rangaswami (1993) as well as Harit and Taylor
( 1 995).
Very few mathematical programming models have been proposed. This is not
surprising given the complexity of the problem both from a conceptual and computational
point of view.
Most of the research in the area of mathematical programming of
materials handling systems has focused on optimizing materials handling equipment and
not the whole materiaIs handling system. A good review of such practices is provided by
Rembold and Tanchoco (1994).
An exarnple o f an algorithm for the selection and assignrnent of materials
handling equipment is that of Hassan et al. (1985). The problem is fomulated as an
integer programming model with the objective of minimizing the total operating and
investment costs o f the selected equipment. The model only explores the assignment of
equipment for departmental moves (Le., transportation).
Other materials handIing
operations are not considered.
Recent work has made substantial strides in developing models that deal with the
materials handling system as a whole rather than with individual pieces of equipment.
Gupta and Dutta (1994) developed a methodology for linking product design with
manufacturing logistics design activities. In particular, it was proposed tha; materials
handling needs be considered within the manufacturing systems design through
concurrent engineering.
The authors argued that "manufacturing logistics design should be undertaken as
soon as the product design stage is started".
Five key product variables are used to
describe a product's characteristics: complexity, precision, diversity, batch sizeflot
size/run-length and mass o r linear dimension. These characteristics are defined in t e m s
of the choice of manufacturing technology associated with the product's conception,
realization, disposition and disposal. Each materials handling system contains within it
five subsystems: loadinghnloading at the workplace, transportation, handling/rehandIing
away from the workplace, inspection module and storage/retrieval device. Each of these
subsystems is composed of a number of sub-operations such as orientation change,
position change, quantity change, sequence change and timing change. The attributes of
the product/process combination, i.e. choice of technology, are related to the materials
handling system requirements through a five point rating scale.
The appropriate
materials handling system is then selected through a weighted rating method.
This concept was expanded by Atmani and Dutta (1996) into a mathematical
model. A 0-1 integer prograrnming model was proposed to maximize the 'adaptability
factor'.
The 'adaptability factor' maps the product/process design ont0 the materials
handling system design. It was formally defined by Gupta and Dutta (1994) as "the ratio
of basic motions/movements that are required by a new product to those available in the
current manufacturing logistics system". The methodology outlined previously by these
authors fonned the base for the mathematical model.
Other integrated approaches have been praposed. Noble et al. (1998) developed a
model that integrates materials handling equipment selection and specification (materials
handling interface equipment included) and path/load dependent unit load size.
The
formulation attempts to minimize the operating and capital cost of materials handling and
necessary interface equipment.
Although the materials handling operations are not
defined, the model appears to only consider transportation between workplaces. Paulo et
al. (1999) presented a methodology to consider the operation allocation and materials
handling system selection problems jointly. The work represents an important first step
towards developing an integrated approach to solving these two manufacturing problems.
2.2.
Commentary on Previous Work
The recent work on the development of more integrated rnodels in operations
allocation and materials handling system selection is indicative of a trend to mode1 more
realistic problems in a manufacturing system. These problems are undoubtedly more
cornplex and difficult to mode1 and solve. This is part of the reason why most past work
has dealt with individual problems.
However, the realization of the benefits of an
integrated approach warrants new research of models that are integrative in nature.
In the past, the operation allocation and materials handling system selection
problems have been considered separately. However, it is obvious that the solution to
one of these problems is influenced by the solution to the other problem. This has been
evidenced by the attempt of previous researchers to include the materials handling costs
in their operation allocation models. In addition, a necessary input to most matenals
handling system selection models is the operations assignments that result from the
solution to the operation allocation problem. It is obvious that these two problems are
both members of a larger system affected by various interrelationships.
This work
attempts to bridge these two problems by explicitly considering both of thern and their
interactions.
The work presented here encompasses and enlarges the methodology
proposed by Paulo et al. (1999).
The work builds upon two existing models: the mode[ of the joint cell formation
and operation allocation in a cellular manufacturing by Atmani et al. (1995); and the
materials handling system selection model by Atmani and Dutta (1996). These models,
which f o m the foundation of this work, were revised and suitably modified for the scope
of this work. In the case of the materials handling system selection model, the changes
were substantiai, resulting in a mode1 that is distinctively different fiom the previous one.
Sorne of the changes were introduced to allow the integration of the two models.
3.1.
Sub-Mode1 1. Operation Allocation
The model of the joint ce11 formation and operation allocation in a cellular
manufacturing system, proposed by Atmani et al. (1995), was simplified. Specifically,
the model was reduced to an operation allocation model. The ce11 formation component
was eliminated in an attempt to reduce the complexity inherent in bridging the two
models. As such, the constraint that ensured that a specific machine was only assigned to
one specific ce11 was eliminated.
There were further modifications in the objective function and constraints. One
modification was the addition of the machine setup cost to the objective hnction. This
ensures that we now have a more complete description of the total cost.
The unit
refixturïng cost present in the original model was combined with the unit operation cost
since these constituted sums over identical sets o f indices.
As such, the new unit
operation cost includes both the unit manufacturing cost and the unit refixturing cost.
The same is true for the constraint that ensures that the total time of the operations
assigned to a certain machine does not load the machine beyond its capacity. The unit
operation time now includes the unit manufacturing time and the unit refixturing and
defixturing times.
This modified model is essentially the same as that proposed by
Atmani (1 995).
The modified 0- I integer prograrnrning model is developed below.
3.1 .1. Mathematical Formulation
Assume that there is a set o f
11
part types labeled with the indices i = 1, ..,, n,
where the part type i has the known and uniforrn demand diover the planning period. A
part type i can be processed under the different process plans p
=
1,
....P(i).
For a
process plan p~ Pfi) of a part type i, the manufacturing operations are represented by the
indices s = I , ..., S(ip). There is a set o f rn machines labeled with the indicesj = 1, ..., m.
The set of machines that c m perform manufacturing operation s of a part type i under
process plan p is given by Jip,.
The operation allocation model involves the assignrnent o f operations of each part
type to appropriate machines to minimize the total costs of manufacturing operations,
machine setups and rnatenals handling. The 0-1 decision variables are denoted by X,(ip),
where X,(ip)
=
1 if operation s of a part type i is processed under plan p on machine j and
zero otherwise.
The operation cost is given by E,(X,i(ip)):
where OCq(@) is the known cost of operation s o f a unit of part type i on machine j under
process plan p. This includes both the manufacturing cost and the refixturing cost.
The machine setup cost is given by -(Mi):
where SC, is the known setup cost for machine J and the auxiliary variable M, takes the
value o f one if machine j is selected and zero otherwise.
planning period is assumed.
Only one setup cost per
Since these machines are operated under a flexible
manufacturing system, it is assumed that the only significant setup cost is the initial one
where the machines must be programmed and equipped with the required tools.
Finally, the materials handling cost is given by ~ { X s j / i p ) ) :
where T,- is the cost of moving a unit of part type i from machine j to machine j for the
next operation. Since &(X,(ip)) is a nonlicear hinction, the linearization technique given
l
in Taha ( 1992) is applied. This prescribes replacing É 3 ~ ( i p )with:
where L,(ip)
is a new 0-1 variable satismng the following two sets of constraints:
Note how the above set of constraints ensure that L,fip)
takes the value of one if and
only if a unit of part type i is moved to machine j for operation (s+i) under plan p, after
performing operation s on machine j under plan p.
The objective of the mode1 is therefore to determine the values of Xq(ip) and
Lufipl that will rninimize the total operating, machine set-up and materials handling
costs. This is mathematically expressed as:
The constraints are developed next. The first constraint set ensures that each part
type is processed under a single process plan, and it is given by:
where Z(ip) = 1 if part type i is processed under process plan p and zero othenvise.
The next set of constraints ensures that once a process plan is selected for a part
type. each operation in that plan is processed on only one of the available machines. It is
given by:
The third set of constraints ensures that if machine j is selected then at least one
operation must be assigned to it. It is given by:
The next set of constraints ensures that the total time required by the operations
allocated to a machine j, once it is selected, does not exceed the machine's know-n
capacity. It is given by:
where t,(ip) is the time to perforrn operation s of part type i on machine j under process
plan p.
The two sets of constraints, (IO) and (1 l), ensure consistency between the
ailocation of operations of the part types to machines and the selection of machines.
Assembling the above, we get the folIowing complete statement of our 0-1
mathematical progamming model of the operation allocation model, which is designated
P(0A): Minirnize
Subject to
The assignrnents determined by the model (Le., the X&))
are then summarized
in the matrix A,,, where an element of A,, is equal to one if operation s of part type i is to
be perforrned at machine j, and zero otherwise. This matrix serves as an input to the
materials handling system selection model.
3.2. Sub-model2. Materials Handling Sysfem Selection
The current implementation of the materials handling system selection model is
significantly different fkom the original model by Atmani and Dutta (1996). The original
model was used as the basis for the current model. However, a number of significant
modifications were introduced, The model developed in this section shares much of the
conceptual frarnework o f the previous model, but is irnplemented much differently. The
changes derive from an evolution in the mode1 development as well as ftom the goal to
integrate the operation allocation model with the materials handling system selection
model.
The notation was modified to accommodate the interfacing of this model with the
operation allocation model. It is necessary that cornmon elements such as part types and
machines be represented by the same indices to facilitate communication between the two
models.
As it was the case with the operation allocation model, the ceIl component of the
materials handling system selection formulation was removed. Therefore, the constraint
limiting the number of pieces of materials handling equipment assigned to each ce11 was
also removed.
The new implementation of the 0-1 integer prograrnming model is developed
beIow.
3.2.1. Mathematical Formulation
Assume the same set of rr part types as defined in the operation allocation model,
labeled with the indices i
=
1, ..., n, where the part type i has the known and uniforrn
demand di over the planning period. A part type i can be described in terms of five key
product variables that define the choices of rnanufacturing technoIogy associated with its
conception, realization, disposition and disposal. These are labeled by indices t
=
1, ...,
T m . In our case 7'0= 5 and the key product variables are complexity, precision, lot or
batch size, diversity and mass or linear dimension. Most of these are easily measured
parameters to rnanufacturing engineers and managers. For example, precision c m be
readily measured in terms of tolerances.
i-iowever, complexity can be difficuh to
measure. For the purpose of this thesis, it is assumed that the information embodied in
the shapes of part types is the rneasure of complexity. More precisely, complexity is
measured based on information theory. it measures the minimum number of bits of
information needed to describe a part. In most situations this includes geometrical and
dimensional information. Details of its quantification are presented by Ayres (1988).
There is a set of nr machines labeled with the indices j = 1 , ..., m. At these machines, the
required manufactunng operations for a part type i are represented by the indices s = 1,
..., S(i). The process plan index p is dropped from this model since a plan has already
been selected by the previous model.
The major materials handling operations, h
= 1,
..., H, where in our case H = 5,
are load/un load at the machine, transportation between manu facturing processes or
machines, handling/rehandling away from the workplace, inspection and storage and
retrieval. Each such operation is associated with a number of sub-operations labeled as h
=
1, . ..,
fi, where
in o u case
fi = 6.
These are orientation change, position change,
quantity change, sequence change, timing change and "no change". Simply explained, an
orientation change invoIves rotational change or movement while a position change
invoIves Iinear change or movement. Sequence change occurs when the order of part
types is modified. Timing change involves a change in cycle time between processing of
part types. A number of materials handling equipment are available to perform these
matenals handling operatiodsub-operation combinations. These are labeled as e = 1, ...,
E.
The 0-1 decision variables are denoted by
Yhhjs(i),
where Y,&eJs(r)
handling operation h, which is vsociated with sub-operation
=
1 if materiais
h, requires matenals
handling equipment e at machine j where manufacturing operation s of part type i is
performed.
The objective is to generate the optimal materials handling system selection for a
given mix of part types based on the padprocess combination and the choices of
materiak handling equipment available. Thus, we would like to maxirnize:
where
2[wcr

4T
where IV&;, is a measure of the ability of a materiais handling piece o f equipment to
handle a certain operatiodsub-operation combination while W,,and
& relate
the key
product variables to the materials handling equipment and the part type, respectively.
The parameter Cciis a measure o f the compatibiiity of a piece o f equipment and a
part type. The fraction part of the expression evaluates to a value between O and 1. The
maximum allowed value for the difference behveen each individual pair of WC,
and
4 units. Since the absolute value of this difference is summed over t
= 5,
=
16~
is
1, ..., T, where T
the maximum value that the fraction numerator can exhibit is 20. The denominator
alwayç evaluates to 20. If the values of WC,and
are as far apart as possible, the value
of the fraction will be 20/20 = 1. However, when this is the case, we want to eliminate
the materials handling equipment/part type combination from consideration. Since we
are maximizing the objective hnction. what we really want is for the value of C.,to be as
small as possible for this situation. Therefore, the fraction is subtracted from 1 to obtain
the value oFCei. As such, this parameter evaluates to a number between O and 1, where O
indicates incompatibility and 1 indicates complete compatibility. Incompatibility would
occur for a situation where the values of WC,
and
R.,are as far apart as possible,
which
signals that the materials handling equipment is unsuitable to handte that part type.
and
Complete compatibility would occur when the sum of the differences between WC,
[Vitevaluate to O.
In this case, Cci
evaluates to a value of 1, which affords the greatest
maximization of the objective function. In essence, since the objective hnction is to be
maximized, the model forces Cci to be as close as possible to a value of 1. In tuni, this
forces the WC,
and
II,ratings to be as close as possible in values.
This insures that the
model attempts to match as well as possible the materials handling equipment and the
part types it will service. For most situations, the parameter evaluates to a numerical
value between O and 1, indicating some degree of compatibility.
Integer scales are used to assign values to the W parameters. The rating scales
range from O to 5 for W,,,ii;,and WC,,and 1 to 5 for
%l.
The interpretation of the values is
given in Tables 1 , 2 and 3.

The three rating factors (Whl;erWri and &.) are largely subjective and a fomalized

the key product variables are given in a paper by Ayres (1988).
The rnatrix As, is derived fiom the output of the operation allocation model where
any element from that matrix equais one if a manufacturing operation s for part type i is
performed at machine j and zero othenvise. This parameter is the link between the two
models. It provides a necessary input to the materials handling system selection model
by describing the manufacturing operation assignments for each part type.
The parameter ah&, equals one if materials handling operation h, which is
followed by sub-operation h, is required at machine j where manufacturing operation s of
part type i is performed and zero otherwise. This parameter is a new addition to the
model, which describes the required materials handling operations/sub-operations
correspondent to the manufacturing operations. This was a necessary addition since the
goaI of the model changed. The previous mode1 was a stand-alone model that chose the
best general materials handIing system.
Tt was unaware of part type routings and
manufacturing operations. The current model is no longer stand-alone. One of its inputs
is the matrix summarizing the operations allocations. As such, it is necessary to supply
the model with information concerning the materials handling operations that must be
perfonned at a machine where a manufacturing operation has been assigned.
This
information is inputted by the user afier the machine selections and operation
assignments are known.
The first set of constraints ensure that only one type of materials handling
equipment is chosen to perform a materials handling operationisub-operation
combination required for manufactunng operation s of part type i at machine j. It is
expressed as:
This constraint also ensures that a piece of materials handling equipment is only assigned
when it is required. In other words, the decision variable Y,lhe,S(i) is oniy set equal to one
when a materials handling operatiodsub-operation is required.
The next set o f constraints ensures that a piece of equipment e is only chosen after
another piece of equipment ê has been assigned. This set of constraints is provided to
allow precedence relationships that rnay exist in the assignment o f materials handling

The third set of constraints ensures that if a piece o f materials handling equipment
is chosen, then at least one materials handling operatjonlsub-operation combination must
be perfomed by that equipment. It is mathematically expressed as:
The next set of constraints guarantees that the total time for al1 jobs assigned to a

An example is presented to demonstrate the viability of this work and o f the

4.1,
The Operation Allocation Problem
Assume that we have i = 1 , ..., 14 part types to be manufactured with demands as
listed in Table 4. The part types have P(1) = 2, P(2) = 3, P(3) = 2, P(4) = 2, P(S) = 2,
P(6) = 1 , P ( 7 ) = 2, P(8) = 2, P(9) = 1 , P(10) = 3 , P(11) = 2, P(12) = 2, P(13) = 1 , P(14) =
2 different process plans.
Each process plan c m include up to four manufacturing
operations. There are j = 1 , ..., IO machines with known capacity bj = 57,600 and setup
costs as listed in Table 4. Each of these machines is capable of performing operations
required by the process plans. For example: under process plan p = 1 , part type i = 1 has
S(11) = 3 operations with indices SE { 1 , 2, 3). Operation s = 1 of process plan p = 1 for
part type 1 can be completed on any of the machines j d l l l = { 1 , 3, 4, 7, 10) while
operation s = 2 can be completed at any of the machines ~ E J I / ?= (1, 5 , 7, 8) and

To simplify this exarnple, we assume that the cost of moving a part from one

Table 5. Cost of moving a unit of part type i from machinej to machinef, T,fi(i = 1.
...,14).
The problem was solved with the aid of Lingo. The results obtained are presented
in Table 6. The results indicate that machines 1 and 3-8 were selected to process the 14
part types under one of their possible process plans. For exarnple, part type i = 1 is
processed under plan p = 2 where operztion s =1 is perfonned at machine j = 3 and
operation s = 2 is performed at machinej = 1. Similar interpretations can be made for al1
other part types. These results are stored in As, to serve a s input to the materials handling
system selection model. The total cost is 7,752, which includes processing, machine setup
and transportation costsThe machine utilization percentages are quite small, indicating that the machine
availability exceeds by far the time rzquirements of the processing operations. In a more
realistic situation, the time available on the machines will not greatly exceed the time
requirernents of the operations.
The saine exarnple was re-solved with machine capacities that were significantly
reduced. For this case, the machine availability of machines j = 3 and j
=
7 were set at
480 time units, while the time available in each o f the other machines was restricted to
980 time units. Al1 the other case study data remained unchanged. Once the problem
was
solved, a new solution was obtained and it is presented in Table 7.
The solution to this modified case shows some interesting differences from the
solution to the previous example where there was ample machine time available. The
first difference that one might notice is that for some part types a different process plan
was chosen. No longer is it possible for the process plan with the absolute lowest cost to
be always chosen. Due to constraints in machine availability, the model is forced at
times to choose process plans yielding slightljr more expensive processing costs.
Another major difference and one that is expected, is that the machine utilization
percentages increased. Further, in this example, al1 available machines were selected.
Again, this was necessary to satisQ the machining time requirements. Please note that
for a Few of the machines, the utilization is extremely high. It is assumed that machine
allowances were factoreà into the machine availability data used in the example. This
means that if one expects a machine to have an uptime of 90% then the 980 time units
made available to the model actual represent IO89 time units of real time.
A price must be paid for the time constraints on the machines.
As it was
discussed above, the limited machine availability forces the mode1 to choose more costly
process plans. For this exarnple, the new value of the objective function was 1 1,789.
This represents an increased cost of 4,037.

IR?table for the case study example.
Frorn Table 8 we can observe that, for example, part type i = 2 has a high degree
of complexity and precision. This rneans that this part is composed of a large number of
geometrical and dimensional features and it must be manufactured to close tolerances.
The very low score for diversity indicates that this part type belongs to a part farnily
composed of a small number of products. We also know that this part type is
manufactured in medium-size batches and it is large in dimensiotdmass. A similar
description of each part type can be inferred from Table 8.
The fundamental materials handling operations, h
=
1, ..., 5, are loadunload,
handlinglrehandling, transportation, inspection and storage/retrieval.
Each of these
operations is associated with one or more sub-operations such as orientation, positioning,
quantity, sequence, timing or none. These are labeled with the indices h = 1, ..., 6. For
this example it is assumed that we have e = 1, ..., 9 different types of materials handling
equipment.
Each of these is available for 57600 time units. The materials handling
equipment is rated against the choices of manufacturing technology as seen in Table 9.

Table 9 indicates, for exarnple, that the available robots are best suited to handle
part types with a high degree of complexity and precision, a low degree of diversity and
large batch sizes. The light-load robot is best suited to handle part types of very small
mass/linear dimension while the heavy-load robot is best suited to handle large and
heavier part types. In other words, the ideal part type for these robots to handle is one
that is described by a large number of geometrical and dimensional features, requires
close tolerances, belongs to a part family with a low number of members and is produced
in large batches.
The materials handling equipment is also rated on its ability to perforrn the
various materials handling operationkub-operation combinations (Table 10). Again,
using the robots as an example, we can see that Our particular robots are capable of
performing the various operations required for loadhnload and handle/rehandle.
The
degree to which these are able to perform the various operatiodsub-operation
combinations varies. For exarnple, the robots excel at load/unload operations with the
exception of those requiring a quantity change. This is understandable since robots are
often fitted with grippers and unable to accommodate a varying number of part types
from cycle to cycle. The same is true for handlekehandle operations.
The unit times required by the various types of materials handling equipment to
perfornl the matenals handling operationkub-operation combinations are given in Table
11.
The materials handling requirements are derived fiom the output of the operation
allocation problem. Table 12 summarizes the materials handling requirements for this
case study example.
T h e problem was formulated in Lingo and then solved. The results obtained from
the Lingo solution of the materials handling system selection are summarized in Tables
13 and 14.
The resutts indicate that the mode1 behaves in an expected manner, choosing
sound materials handling assignments for the part types.
For example, if we look
carefully at the materials handling assignments for part type 2, we can reason why the
chosen assignments are the correct ones. The load/unload operations were assigned to
the heavy-load robot. This is not surprising since part type 2 is a heavy and large part, of
very high complexity and precision.
The AGV was chosen for the transportation
operations. Again, this is not surprising given the characteristics of part type 2.

Table 13. Solution to the niatcrials handling systeiir seleclion probleiii.
A more unexpected result is that the inspection operation was assigned to the
human. One might be surprised that a heavy part was assigned to the human. This
obviously raises questions regarding potential ergonomic problems. However, for this
example, the human was the best-suited option for an inspection operation requinng an
orientation change. No other choice of materials handling equipment cornes even close.
In addition, humans are well suited to handle part types of high complexity and precision.
Similar interpretations can be made for the remaining assignrnents of the part types.
At times, the results may not be as simply justified. This is because the actual
assignments are a result of three ratings. As such, it is possible that a piece of equipment,
with the highest rating for a certain key product variable, is not chosen for a part type
exhibiting a high degree of that key product variable. This would be the case if that piece
of equipment rates poorly for the materials handling operations required by the part type.
The three parameten, le,,W, and W + I ;are
~ at the heart of the materials handling
system selection model. These parameters are largely subjective ratings of relationships.
Therefore, it is important that a sensitivity analysis be completed so that we may more
clearly understand their impact on the model's assignments.
Parameter
%-[is studied in great detail since it provides the link between product
design and rnanufacnuing design. Parameter Wcris partly handled by drawing a parallel
to the insight gained by the sensitivity analysis of
q.,.Finally,
some experimentation
with parameter CVlli;edemonstrates its impact on the assignments chosen by the model.
One c m draw a hypothesis regarding the impact of the rating factors from an
elementary analysis of the model's objective function. Since the final assignments are
lax-gely dependent on the values of the three factors, in general one may expect that a
single change to one of the factors wiI1 not cause an immediate change in assignments.
As an example, parameters
grand WC,are used in the evaluation of C,,
which measures
their differences for the various key product variables. As such, one will expect that a
small change in one of these parameters will not greatly impact the model's assignments.
One can predict that a significant change in one of these parameters must occur before
the solution is changed. In other words, one may expect the model to react to changes in
the factors, but without being overiy sensitive to these changes. Of course that this
hypothesis is based on generalized conclusions. There are always exceptions and if the
rating that is being changed has an impact on a constraint that was "tight" at the solution,
then we c m expect to see a change in the mode's assignments.
These hypotheses were tested and the results fiom the sensitivity analysis follow
below.
Sensitivity Analysis of
5.1.
A sensitivity analysis was conducted on
e,to study the response of the mode1 in
ternis of materials handling assignments to the differences in
?&,ratings.
A large number
of runs were conducted. The &Il listing of these can be found in Appendix II. A subset
of these is presented and discussed below.
The examples presented for the sensitivity analysis are based on the case study
Each key product variable for part type i = 2 was assigned a value of 2
example.
(indicating a low vaIue of that key product variable) or 4 (indicating a high value of the
key product variable). The total number of combinations, and therefore trials, were 25 =
32. The
F&,
ratings for every other part type remained unchanged. Al1 other ratings and
data also remained unchanged from the case study example. This meant that the only
paranleters that changed over the trials were those for part type i = 2.

From the results obtained and presented in the Table 15, one c m analyze the
model's response to changes in
CC,values.
As such, we can take pairs of runs and
compare the resulting assignments. For example, if we look at runs # 1 and #2, we can
observe that the only value that was changed was that for lineadmass dimension. It was
changed from a value of 2 (low score) to a value of 4 (high score). From the resulting
assignments, we can see that for loadhnload operations, the human was replaced by the
heavy-load robot, As weil, for the transportation operations, the iight beIt conveyor was
replaced by the roller-bed beit conveyor. These constitute sound assignments since our
part type was changed fiom light and srnaIl to heavy and large. The assignrnents for
inspection and storage and retrieval operations remained unchanged. This indicates that
these assignments remain the most appropriate for the part type.
When the value for batch size was increased (cornpiirison of runs # 1 and #3) and
the values of all the other key product variables remained at 2, we observe that the onIy
change in assignments were that for the load/unload operations. In this case, the human
was replaced with the light-load robot. This seems appropriate since the robot is better
suited to process larger batch sizes.
A cornparison of runs # 1 and #5, where oniy the value assigned to diversity is
changed, shows that the original assignments remain optimal. This indicates that the
chosen assignments for this part type, when al1 other values for the key product variables
are set to 2, are optimal for both low and high values of diversity. However, the same is
not true for the case when the values of al1 the other key product variables are set to 4.
Comparing runs #28 and #32, we can observe that one of the assignments changes. For
the transportation operation, the mode1 chose an AGV for the case where the diversity
value was low (run #28) and the roller bed belt conveyor for the case where the diversity
value was high (mn #32). This makes sense since an AGV will usually require fixtures
for the part type and as such, it is better suited to a part type of low diversity. On the
other hand, the rolled bed belt conveyor can accommodate part types of high diversity
quite easily.
When we change the value of precision whiie keeping the values of al1 other key
product variables constant at a value of 2 (runs fC1 and #9), we observe some changes in
the assignments. The hurnan was replaced by a light-load robot for the Ioad/unload
operations and the light-duty belt conveyor was replaced with an AGV for the
transportation operations. An AGV is better suited to handle part types of high precision
(compared to a conveyor), even though it is hard to justiQ its use on a part type of low
complexity and low mass and dimension. However, given the set of materials handling
equipment that our model was forced to choose from, it has determined that this piece of
materials handling equipment is the best choice out of the set. One should also keep in
mind that the model does not consider costs and as such, the model ignores any cost
considerations from the assignment choices.
Finally, we can look at the case where only the value of complexity is changed.
From observing the assignments for runs #1 and # I 7 we can conclude that the model
responded to the change in complexity by choosing a different set of assignments. The
increase in complexity resuIted in the replacement of the human with a light load robot
for the load/unload operations and of the light-duty belt conveyor with an AGV. The
discussion presented for precision can be made in this case as well. While the AGV may
not be the ideal choice of materials handling equipment, it is the best suited out o f the set
of materials handling equipment that we made available to our model.
Many other comparisons can be made fiom the data presented in Table 15. To
avoid repetitiveness, these are not presented here. There were also more examples (nuis)
performed. These are included in the Appendix II. Overall, one will find that the model
responds correctly and as expected to changes in the values of the key product variables
for the parameter
5.1 .l.
Detailed Sensitivity Analysis of
W~
The comparisons derived from Table 15 were for changes in
II,of 2 units (values
of 2 and 4). In many situations, a difference of 2 units was enough to result in new
assigmnents. However, this was not always the case. It is worthwhile to investigate this
observation more carefùily to better understand how sensitive the model is to the changes
in the key product variables.
Looking back to Table 8, we can see that part type i = 2 from Our case study
example has the following ratings for

rrtings for part type i = 2.
To test what magnitude of a change in the key product variables is required to result in a
new set of assignrnents, sorne test nuis were performed for different values of complexity
and mass/linear dimension.
In the first case, we ran the model for al1 possible values of complexity while
keeping the values of the remaining key product variables unchanged. The results
indicated that a new set of assignments would only be generated when the value of
complexity was equal to or less than a value of 2. This implies that a change of 3 units (5
- 2) was
necessary for the model to choose a new set of assignments. In the new set of
assignments, the AGV was replaced with a roller bed belt conveyor.
For the second case, we tested for al1 possible values of massAinear dimension
while keeping the values of al1 other key product variables unchanged. in this case, it
was found that a change occurred when the value of masdlinear dimension was lowered
to 2 or less from the original value of 4. This indicates that only a change of 2 units was
required for new assignments to be generated.
Other similar tests were conducted. The testing indicates that usuatly a change of
2 or 3 units is required before a new set of assignments is generated by the model. This
means that the model responds to changes in the
q,val:
-s, but it is not overly sensitive.
In other words, small changes in the product design are possible without the need for a
new set of materials handling equipment. This mirnics what one typically expects to find
in a real world situation.
5.2. Sensitivity Analysis of Wd
A sensitivity analysis for WC,was conducted, but not as extensively as for
&,.
A
total of 10 runs were conducted. For the first set, the light-load robot was considered
while its complexity rating varied fiom 1 to 5 . In the second set of runs, the AGV was
strrdied as its mass/linear dimension rating was set to values between 1 and 5. This small
set of runs is far from being an exhaustive study of the effect of this parameter on the
solution. However, by studying the effects of two key product variables on two different
types of materials handling equipment, one can draw some preliminary conclusions of
interest.
5.2.1. Effect of the Complexity Rating of the Light-load Robot
In this set of experiments, the compiexity rating assigned to the light-load robot
(Le. W,, =
W i l )was varied between a very low value of 1 and a very high value of 5 . The
effects of this change on the overall solution were studied. Since the light-load robot was
only used for Ioadunload and handlelrehandle operations, these were the only operations
where different assignments occurred. The results from the various runs are summarized
in Table 17.
Some empirical conclusions cm be drawn kom observing Table 17. The most
important conclusion is that the mode1 responds to changes in the parameter W,,, but it is
not overly sensitive. For example, if we look at part type i = 1, we see that for a value of
complexity equal to 1, the human is the optimal materials handling equipment. When the
value of complexity is changed to 2, the hiiman remains optimal, but the light-load robot
is also optimal. For values of complexity equal to or greater than 3, the human is the
optimal assignment. This type of occurrence is common. In most instances, when the
complexity change leads to a new assignment, we encounter a situation where at the
transition point, we have two optimal choices of matenals handling equipment.
Also interesting is that for certain part types, the chosen materials handling
equipment type remains unchanged for any value of complexity. This means that the
chosen matenals handling equipment is very compatible with the part type. Although we
Vary the value of complexity, the previously chosen matenals handling equipment type
remains the best-suited equipment type for the part type.
5.2.2. Effect of the MasdLinear Dimension Rating of the AGV
For the second set of runs in the sensitivity analysis of parameter WC,,the
masdlinear dimension rating o f the AGV was tested at al1 levels between 1 and 5 (i-e. Wer
=
w&).In this case, it is only necessary to study the assignments for transportation and
inspection operations since these are the only two major materials handling operations
that the AGV perforrns. The assignments obtained fiom the various runs are summarized
in Table 18.
Observation of Table 18 reveals that a change in value for the mass/linear
dimension rating o f the AGV has almost no effect in the assignments deterrnined by the
model. There are only two part types for which a change in the value of mass/linear
dimension affects the output of the model. These are part types i = 4 and i = 6, As it was
found in the previous set of mns for the light-duty robot, a change in the final
a s s i v e n t s involves a transition point where bvo pieces of matenals handling equipment
are optimal.

At the first look, it is somewhat surprising that the change of value in massllinear
dimension for the AGV does not affect the assignments more strongly. However, one
must remember that masdlinear dimension is only one of the five key product variables.
If the match between equipment and part type for the other four key product variables is
good, then a change in massAinear dimension alone may not sufficiently affect the model
to result in a new set of assignments.
One can note that the AGV is only one of five available types of materials
handling equipment that can be used for transportation and inspection operations. As
such, it is very likely that a part type can be closely matched with one of the available
types of equipment. If the compatibility between the part type and a piece o f matenals
handling equipment is great enough, then a change in one of the key product variables in
unlikely to cause a change in assignments.
In general, small changes in the rating of a key product variable for a given part
type have little effect on the final set of assignments. Large changes in the rating are
rnuch more likely to affect the assignments fiom the model. However, if the
compatibility behveen a part type and a piece o f equipment is high, then a change in the
value of just one of the key product variables is much less likely to result in a change of
assignments.

Again, a total of ten runs, divided into two sets, were conducted. The first set
studied the effect of the (un)Load/Onentation rating of the light-load robot (Le. Wl1he=
W I I I on
) the assignrnents. The second set of runs studied the effect of the
TransportatiodQuantity rating of the roller bed belt conveyor (i-e. Wh\;e= WJJ6)on the
materials handling assignrnents.
5.3.1. Effect of the (un)Load/Orientation Rating of the Light-load Robot
As can be observed fiom Table 19, the effects of the (un)Load/Orientation rating
of the light robot were as predicted. The results from the test runs show that the mode1 is
capable of responding to changes in the
ratings, without exhibiting over-sensitivity.
The results also highlight the fact that the mode1 behaves as expected by choosing the
optimal assignments.
For most of the part types, the assignments remained unchanged for al1 values of
the (un)Load/Orientation rating of the light robot. This indicates that the original
assignrnents were the best possible assignments, while the next best assignments were far
behind it. This also indicates that in order to cause a change in assignments, it is
necessary to change more than one rating.
For the few part types where the original assignments were replaced by new
assignments, the change was progressive. At the interface between assignments, hvo
optimal assignrnents were chosen for a rating. An example of this is part type i = 7.
From Table 19, it can be seen that the human is the preferred choice of materials handling
equipment for un(Load)/Orientation values between 1 and 3. For a rating equal to 4, the
model chose two optimal pieces of materials handling equipment, the human and the
light-load robot. When the rating is further increased to a value of 5, the optima1
assignment becornes the light-load robot. Please note that part types i =6 and i = I I are
not present in Table 18 because these part types do not require any (un)Load/Orientation
operations.
5.3.2. Effect of the TransportationfQuantity Rating of the Roller Bed Belt
Conveyor
The results obtained for the mns conducted to study the effect of the
TransportatiodQuantity rating of the roller bed belt conveyor are summarized in Table
20. OnIy those part types requiring any Transportation/Quantity operations are listed in
the table. It is for this reason that part types i = (2, 5 , 7, 8 , 9 , 1 1, 12) are not listed in
Table 30.
There is one case, that of part type i = 3, where at the transition point, two different types
of materials handling equipment are optimal. However, for al1 other part types, there is
no smooth transition as has been observed quite often in other runs of the sensitivity
analysi S. This happens because when the TransportatiodQuantity rating of the roller bed
beit conveyor is set equal to 5, it assumes the highest rating for that
operatiodsuboperation combination of al1 types of materials handling equipment.
Essentially, it tells the model that the roller bed belt conveyor is the best piece of
materials handling equipment to perfonn the required materials handling hnctions,
which in this case is the TransportatiodQuantity function. As such, there is a strong bias
for this type of rnatenals handling equipment to be assigned to part types requinng those
functions.
Again, we can observe that in general, the mode1 responds to changes in the rating
value, but is not overly sensitive.

A program was created to simplify the use of the developed models and to
iIlustrate the potential for this work as an industrial application. The program was coded
with Visual Basic 5.0 and interfaces with Microsoft Access 8.0 and Lingo 5.0. The
program is capable of handling any problem size. Any limitations to problem size are
imposed by the number of records that Microsoft Access 8.0 can handle and the number
of constraints that Lingo 5.0 c m solve. The larger the problem, the more random access
memory will be required for the successfiil operation of Microsofi Access and Lingo.
The full code listing can be found in Appendix IV.
The Solver program fûlfills three major goals. tt allows access to the models data
for creation or modification, it solves the models and it produces reports containing the
solution to those models. The data creation or editing is allowed through Microsoft
Access. One single database called OA.MDB holds al1 the data that the two models
require. The models are solved when the SoIver program calls a Lingo runtime library
that provides access to Lingo's solving capabilities. A Lingo script file was created for
each mode1 (see Appendix 1). This script file is passed by the Solver program to the
Lingo runtime library. Finally the output reports are created and c m be viewed and
pnnted fiom within the program.
The program graphical interface is very simple and clean. The main form that is
visible afier launching the program c m be seen in Figure 1. This form consists of several
key components. There is a menu bar and its accornpanying menu items. There are also
bvo buttons that are used to solve the hvo models. Each button is accompanied by a
disptay area where the value of the objective function is displayed once the mode1 is
successfully solved. Finally, there is also an exit button that terminates the application.

The various components in the main window are presented in more detail below.
6.7. The Menu Bar
The menu bar consists of a number of menu entries. The headings in the menu
bar drop down to reveal one or more menu entries. Each menu entry performs a specific
function. This is similar to nearly every other appIication in the Microsoft Windows
platform that contains a menu bar. Each heading and the menu entries it contains are
now described.
6.1 -1. The File Heading
The Fife heading in the menu bar contains two menu entries: Launch Access and
Exit. These entries can be seen in Figure 2.

Figure 2. The File menu entries.
The Launclr Access menu entry will start Microsofi Access with the data file,
OA-MDB,open for editing. This is the recommended way of editing the data when
extensive modifications are required.
The Exit menu entry simply stops the program. It perfoms the sarne function as
the Exit button at the bottom of the form.
6.1 -2.The Data Heading
The Dura heading contains a number of menu entries (see Figure 3). When
clicked, each menu entry will open a corresponding data table from the database
OA-MDB. Not al1 the tables in the database are shown. Some of the tables do not require
modifications. These include those listing the major materials handling operations and
suboperations and the key product variables. In addition, the tabIe containing the
parameter A, is not shown. The data in this table is filled in automatically aAer the
operation allocation mode1 is solved.

As mentioned above, each menu entry under the Data heading will open a
database table. Figure 4 shows such a data table. In this case, the data table shown was
opened by clicking on the menu entry Machines. Various operations can be performed
within that table view. It is possible to add, delete o r edit a record. Other miscellaneous
operations are available through the button bar at the top of the fom.

press the DEL or DELETE key in the keyboard. Other operations are possible and the
button bar at the top of the form explicitly lists these.
A complete description of al1 the tables in the database along with their fields and
requirements can be found in Appendix III.
6.1.3.The Reports Heading
This heading contains two menu entries as can be seen in Figure 5. The

6.2. The Buttons
There are three buttons in the main window. The boxed buttons are used to solve
the hvo models, while the button at the bottom of the window will exit the program.
6.2.1.The Model Solver Buttons
The labels on the buttons clearly indicate their purpose. The top button is labeled
Solve Operation Allocation Problem. When pressed, the program is instructed to pass
on instructions to the Lingo runtime library to solve the operation allocation model. The
comrnands passed to Lingo are presented in a dialog box that is s h o w imrnediately afier
the button is clicked. Figure 8 illustrates this dialog box.

Figure 8. Dialog box illustrating the commands passed to Lingo.
Once Lingo has solved the model and returned command to the Solver program, a
dialog box is activated to infonn the user about the successfulness of the operation. If
Lingo was unable to solve the model, a dialog box wams the user that an error was
encountered. If Lingo was successful, a dialog box such as the one in Figure 9 is
obse~ed.

The main window is then updated to show the value of the objective fùnction.
This is shown in the label beside the solve button. Figure 10 shows the main window
after the two models were solved. Please note that the values of the objective fùnctions
are shown to the nght of the solver buttons.
The process to solve the materials handling system selection problem is similar to
that described above for the operation allocation problem. Again, clicking on the button
entitled Solve Materials Handling Problem will start the solving procedure.
The operation allocation problem must be solved prior to solving the materials
handling system selection problern. This is necessary because the output from the
operation allocation model is used as input to the materials handling system selectîon
model. As such, the program does not allow the Solve Materials Handling Problem
button to perform its action until the operation allocation rnodel has been solved. Figure
1 1 shows a dialog box that is displayed to the user if the second button is pressed prior to
solving the operation allocation problem.

6.2.2. The Exit Button
The third and final button is a simple Exit button. When pressed, this button
causes the program to finish execution.
CHAPTER 7.
The models presented here are planning models that generate some of the design
details required to draw a conceptual design of a rnanufacturing system. As such, these
are not operational models. Currently, the models are applicable to a single cell. The
objectives are to select groups of machines, load those machines to manufacture a
specific group of parts and then select a suitable materials handling system to handle
those parts at or in between the machines. The models were developed in the context of a
flexible rnanufacturing system or cell.
The integrated approach descnbed by this work consists of major phases that are
completed in a sequential manner. In the first phase, the operation allocation model
determines the optimal group of machines to process the part types and then assigns the
operations of the part types to the machines. The assignments are done so that the total
cost of operations, machine set-up and materials handling (transportation) is minimized.
These assignments are then passed on to the materials handling system seIection problem
where they are used as input values.
In the second phase, the materials handling system selection model is solved. The
materials handling systern selection model determines the optimal group of matenals
handling equiprnent to perform a11 the required materials handling operations.
The
equipment is chosen based on its ability to perform the required materials handling
functions and its compatibility to handle part types with certain key product
characteristics. The mode1 considers several important constraints imposed o n the system
such as biases towards equipment combinations and equipment capacity. The result of
the second phase is the selection of the best materials handing system to handle a given
product-process combination.
The sensitivity analysis performed for the materials handling system selection
model shows that the model responds to changes in the rating values (Le., the ratings for
W, and &) but is not overly sensitive. In most situations, a value of four in one of
the ratings will produce the same assignments as a value of £ive. In general, a difference
of two points or greater is required for a change in assignments to occur. This finding is
extrernely important since the values for the rating factors are subjective and will
undoubtedly differ from user to user. The fact that the model is not overly sensitive to
changes in the ratings indicates that two users are likely to reach the same assignments
even though the values they assign to the various ratings may differ somewhat.
The conclusions made fiom the limited sensitivity analysis need to be fiirther
confirmed.
These conclusions were based on the analysis of a single and perhaps
somewhat simple example. It would be extremely interesting to study how the models
react to extreme exarnples with various "tight" constraints. Nonetheless, the preliminary
results fiom the sensitivity analysis are very positive and encouraging.
A Visual Basic program was developed to ease the use of the models and
demonstrate the potential of the work as a practical application in iodustry. The Solver
program allows for data editing, solution to the operation allocation and matenals
handling system selection problems and report generation of the models' output. The
program allows for quick evaluation of what-if scenarios while providing a simple
interface with a small learning curve, even for personnel not familiar with linear integer
programming.
The results of the case study example show that the model can be successfülly
used as a tool for solving the joint operation allocation and materials handling system
selection problems with product design considerations. The computational time required
to solve the models was under one minute on a personal computer (AMD K6-2 350Mhz).
The time will increase for larger and more realistic problems, but it is expected to remain
computationally feasible.
The methodology presented here provides the decision-maker with a rapid
modeling tool to solve the joint operation allocation and materials handling system
seiection problems. The Solver program that was developed is a first implementation of
a rapid modeIing tool to solve both problems. The two problems are solved sequentially
at this point. There is a flow of information from the operation allocation problem to the
materials handling system problem, but there is no feedback. This means that it is not
possible to provide feedback to the operation allocation model and then rerun the models
to fine-tune the overall solution.
This is a recognized shortcoming of the present
implementation of the model to be addressed in future research.
The current implementation of the model offers some flexibility not available in
other models. For a given operation allocation solution, it is possible to experiment with
the product-process combination. For instance, it is possible to identie the materials
handling equipment best suited for a given product design. This is what was done in the
case study example. However, it is also possible to study what product characteristics are
best suited for a specific set or group of materials handling equipment. This provides a
welcomed iink between product design and manufachiring logistics design.
7 1.
Future Research
The current work may be fùrther developed and extended in a variety of ways. Of
course, future researchers' interests will dictate the path, but some of the possible
extensions to this work are discussed below.
The first and most natural extension to the work is to develop a feedback link
between the materials handling system selection problem and the operation allocation
problem.
The main idea is to provide a mechanism by which the goal becomes to
optimize the combined solution to the two problems, rather than the optimization of each
individual probiem. The current implementation of the models already allows for oneway communication between the models.
The output from the operation allocation
problern is used as input to the materials handling system selection. What remains to be
done is to develop a similar link from the materials handling systems seIection model to
the operation allocation model. One could then enter a cyclic iterative process until the
'best' solution to both problems is obtained. Two great challenges to this extension are
developing the feedback link and determining the condition or process that informs the
modeIs to stop iterating.
Another possible extension to the model, and one that requires serious
consideration, is the development of a rigorous method of assigning values to the
currently subjective rating factors of the materials handling system selection model. This
will be a difficult task since the relationships that the ratings attempt to measure do not
lend themselves easily to measurernent.
The materials handling system selection mode1 may also be extended by
considering cost. Presently, the model rnakes no consideration for the cost of materials
handling equipment or the fhctions they perform. As such, one can readily think of the
diIemma that occurs when the mode1 must choose between two equally able pieces o f
materials handling equipment. Since they are both equally 'able', the model makes a
random decision as to which one to choose. In reality, one would choose the lowest cost
option. This is an extreme case, but also one that highlights a limitation of the current
In such cases, it may make sense to extend the model to include cost
model.
considerations.
The Visual Basic program could also be further developed to improve its
functionality and appeal as an industrial application. This would be of even greater
importance once some of the work outlined above has been completed.
When the
complete integration of the operation allocation and materials handling system selection
models has been fully addressed, it might be interesting to improve the Solver program to
make it a viable product for engineers and managers. There are a number of areas where
the program c m be improved. These include user interface design, better handling of
errors, user defined files and paths, etc.
There are other options for fiirther development of the work presented. The ideas
outlined above are just some of the more obvious extensions. It is this author's opinion
that the completion of those would greatly improve upon the work that has been
achieved.
The work described in this report represents an important step in the developrnent
o f an integrated approach to manufacturing systerns design.
An existing operation
allocation model (Atmani et al., 1995) was modified appropriately.
The materials
handling system selection model by Atrnani and Dutta (1 996) was extensively overhauled
and refomulated for the context of this work. The two models were linked and solved
sequentially. A large problern was solved and sensitivity analysis was carried out for the
rating factors in the materials handling system selection model. This analysis showed
that the model tolerates small differences in the values of the subjective ratings, without
generating a new solution. A Visual Basic application was developed to simpliQ the use
of the models. This practical application c m be used as a rapid modeling tool by the
decision-maker.
The integration of the operation allocation and materials handling system
selection models is a very interesting and challenging problem. The work gresented in
this thesis is a first step in developing a thorough solution to that problem. It provides a
base from which future researchers may fùrther develop and extend the current solution
to this integration problem.

Each data table in the database is composed of a number of fields. Al1 tables
contain an ArtroNttmber index that is used as the prirnary key. This field is used to
uniquely identiw each record in the tabIe. Although the use of this field is not required,
its presence allows for the construction of queries, forms and reports.
Each data table is now descnbed in a tabular format.

Please note that Lingo requires that al1 set members be o f type Text, while
attributes of those sets should be of type Number (type Czrrrency is also acceptable).
Also, Lingo requires that the database be registered as a ODBC Data Source
before it can be accessed. The process to register the database is explained in the Lingo
5.0 User Guide (pp. 278-282).
Appendix IV. Solver Program Source Code
The Solver program is composed of a number of different files. Visual Basic
saves each forrn ( f o m attributes and code) in a single file. Similarly, it also saves each
module in a different file. In our case, the source code to Solver consists of 17 files.
There is one project file, one module file and 15 forrn files. Table 42 summarizes the
information about these files.
