Vers l'utilisation des réseaux de Petri temporels étendus pour la vérification de systèmes temps-réel décrits en RT-LOTOS

Abstract : This thesis adresses real-time systems, usinga transformational approach. The timed process algebra RT-LOTOS serves as source language. Extended Petri nets with stopwatches and data serve as target language. Rt-LOTOS to extended Petri nets translation patterns are proposed and formally proved. The transformational approach developed for the control part is extended to the data part. The RT-LOTOS language is enhanced with a suspend /resume operator, thus extending the class of real-time systems that can be modeld and verified . The efficiency of the new approach is demonstrated on various case studies that include comparisons with LOTOS and RT-LOTOS tools that had been developed before. The proposed approach may be applied and extended to other modelling languages, in particular the real-time UML profile TURTLE (Timed UML and RT-LOTOS Environment).
