Towards a mechanical verification of real-time reactive systems modeled in UML

This paper provides a verification methodology for UML-based real-time reactive system models. The verification process can be mechanized in PVS (Prototype Verification System). The motivation for this work comes from the wide acceptance of UML in industry, as a unified notation applicable to the development of object-based systems in a broad spectrum of domains, and the use of PVS for design analysis in large-scale safety-critical applications.
