3. Formal methods in software engineering Improvement in specification and realization process Enhanced precision in syntax and semantics of system definition A lot of different languages, methodologies e.g. Z, objectZ, PUML, (note - UML, OCL: semiformal´) : … Difficult synergy, difficult validation process Problems

4. Goals of FUP Enhancement of analysis/validation process between more specifications analysis/validation process between specification and realizations mathematics logics precision in software specifications and realizations

5. 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

6. 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.

7. Business Process theory …

8. UML theory …

9. UML model transformation into model of theory (example) Individuals = {class1, class2, association1 …} Predicates = {BG(class1), BG(class2), P(class3).. }

10. Formal analyzer Interpretation(UML) |= T1  T2 |- Formula(Interpretation(UML))  T2T1
