A methodological approach to the formal specification of real-time systems by transformation of UML-RT design models

We are motivated to complement our methodology by integrating collaboration diagrams to facilitate the specification of capsules in UML-RT design models. An improved systematic transformation method to derive a correct and complete formal system specification of real-time systems is established. This article aims at integrating temporal requirements in the design stage of the life cycle of a real-time system, so that scheduling and dependability analysis can be performed at this stage. The application of CSP+T process algebra to carry out a systematic transformation from a UML-RT model of a well known manufacturing-industry paradigmatic case, the “Production-Cell”, is also presented.
