Slovak University of Technology Faculty of Informatics and Information Technologies Bratislava, Slovakia www.fiit.sk FUP - Formal Unified Process MSc.Miroslav Líška miroslav_liska@formal-analysis.com
Agenda • 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 logicsprecision 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.
