Real Time UML: Advances in the UML for Real-Time Systems (3rd Edition)

The UML Profile for Schedulabilty, Performance, and Time defines semantic model of real-time concepts. These are divided up into several subprofiles the general resource model, the time model, the concurrency model, the schedulability model, the performance model, and the CORBA infrastructure model. Each of these models has a set of related concepts, represented by stereotypes and properties (tagged values). To use the profile, select (or create) the appropriate classes in your user model and apply the stereotypes. Once these stereotypes are applied, the tagged values may be specific assigned values. Such annotated models can then be analyzed for schedulability. The next several chapters focus on the utilization of the elements of the UML (and RTP) to specify, design, and construct systems.
