UML is a language for specifying, visualizing and documenting object-oriented systems. However, UML statecharts lack precisely defined syntax and semantics. This paper provides a method of formalizing semantics of UML statecharts with Z. According to this precise semantics, UML statecharts are transformed into FREE (Flattened Regular Expression) state models. The hierarchical and concurrent structure...

According to this precise semantics, UML statecharts are transformed into FREE (flattened regular expression) state models. Proper testing pre-orders and equivalences are introduced which allow to equate/distinguish systems on the basis of their interaction with the surrounding environment, abstracting from...
