Engineers are more and more faced to the hard problem of developing more sophisticated real-time systems while time to market and cost constraints are constantly increasing. Current work performed at the OMG on UML standard evolutions to better integrate real-time issues shows both that there is a strong interest on the subject and that current proposals are neither completely satisfying, neither completely compatible. In particular, some available methods (namely ARTiSAN, RT-UML, UML/SDL and UML-RT) provide a good support for parallelism modeling of an application. Nevertheless, they but are often poor to express quantitative real-time features (such as deadlines, periods, priorities...) and are always based on proprietary solutions not obviously fully compliant with the UML standard. So, two important challenges are still targeted: first to define how to support high level real time specification concepts in UML; and, second, to unify them within these proposed by existing tools.
This tutorial will study the current status of the main existing methods and tools and propose some directions to manage the remaining problems.
Audience:
Engineers developing embedded systems, researcher and teachers concerned by software engineering practices for real time systems
Required experience:
Knowledge of the real time system domain and preferably general knowledge on UML.
