1 DEDALE - Development of specifications

An appropriate approach for translating UML to B formal specifications allows one to use UML and B jointly in an unified, practical and rigorous software development. We can formally analyse UML specifications via their derived B formal specifications. This point is significant because B support tools like AtelierB are available. We can also use UML specifications as a tool for building B specifications, so the development of B specifications become easier. In this paper, we address the problem of modelling UML state-charts in B, which has not been, so far, completely treated. We distinguish between event-related and activity-related parts of UML state-charts. We propose deriving the B specification of the event-related part independently with the activity-related part. For this purpose, a new approach for modelling events is proposed; the communication among state-charts is also considered.
