Formal methods in software engineering
Goals of Formal Unified Proces - FUP
FUP methodology
Validation UML models with FUP
Formal-analyzer (usecase model)
FML - Formal markup language
Formal methods in software
engineering
• Improvement in specification and realization process
• Enhanced precision in syntax and semantics of system
definition
Problems
• A lot of different languages, methodologies
e.g. Z, objectZ, PUML, (note - UML, OCL: semiformal´) : …
Difficult synergy, difficult validation process
Goals of FUP
Enhancement of
• mathematics logics precision in software
specifications and realizations
• analysis/validation process between specification and
realizations
• analysis/validation process between more specifications
FUP methodology
• System and its behavior is represented through mathematical
theories – set of formulas (e.g. theory of business process, theory
of UML – customizable modal logic)
• Analysis process is based on verification consistency of
theories, tautological results
• Validation process is based on automatic proving formulas
against selected theories
Validation UML
models with FUP
(formal-analyzer)
• There must be written proper theories for validation, i.e.
business process theory, UML theory
• UML model is translated into model of theory (theory
interpretation) and also they are new theorems specified, which
must be proved
• Formal-analyzer : software tool (currently only analytical
model) which supports mathematical theory specification,
realization, validation. UML will be plugin for parsing UML
models into formal theories.
