RIUNIONE FINALE 08.06.2015
THE AGENDA
1. The car choice problem
2. The research approach
3. The Decision Support Model (DSM) methodology
4. The DSM software
5. Software output
1. THE CAR CHOICE PROBLEM
The choice of buying a car involves a careful evaluation of several
parameters:
SUBJECTIVE ASPECTS:
 Design; Comfort; brand consideration; final use; etc.
OBJECTIVE ASPECTS:
 Purchase price; operational costs; energy and environmental
efficiency; etc.
In addition, the complexity and the limited availability of information
on the variables to be considered may lead to a suboptimal choice.
2. THE RESEARCH APPROACH
The aim is to show how a Decision Support Model
could be useful to suggest the optimal car choice to
decision makers in relation of their mobility patterns.
DECISION MAKER:
Mobility Manager
OBJECTIVE PARAMETERS:
• Private Cost (Lifetime ownership cost)
• Social Cost (noise and air pollution cost)
• Energy Consumption
Finally, the decision-maker choices the option that feels best.
3. THE DSM ALGORITHM
4. THE DSM SOFTWARE
The DSM software is an Excel file including:
A database with the data concerning 60 car models on sale in Italy
 The DSM algorithm
 The DSM interface for different fuel options comparison

The DSM interface
5. SOFTWARE OUTPUT
The DSM graphic and numerical interface
MAIN HELPFUL INFORMATION:
To identify which type of fuel option is more
convenient given a driving pattern;
2. To indicate when the Break Even Point (BEP) of
an investment in an electric or hybrid car is
achieved.
1.
Suggest when for a company should be convinient to introduce green cars in its fleet
