Evaluation of UML-RT and Papyrus-RT for Modelling Self-Adaptive Systems

This paper is an evaluation of UML for Real-Time (UML-RT) for modelling Self-Adaptive Software (SAS) systems. Using a systematic review of the different features of UML-RT (optional capsules, SAP/SPP communication, hierarchical state machines, etc.), we analyse the suitability of the language for modelling structural and behavioural adaptations at design-and run-time. We evaluate these features in the context of their current state of support in Papyrus-RT, an Eclipse-based MDE tool for UML-RT recently developed by the Eclipse PolarSys Working Group. The use of UML-RT and Eclipse Papyrus for Real-Time (Papyrus-RT) for different kinds of adaptation is demonstrated using two real-time system case studies.
