Scenario-Based Consistency Verification of Component-Based Real-Time System Designs
基于场景构件式实时软件设计的一致性检验

For real-time software systems, this paper considers the problem of checking component-based designs for timing scenario-based specifications, which is one of the challenges in real-time computing domain. Firstly the timing scenario-based specifications are specified by UML sequence diagrams with a set of boolean expressions, then the interface automata for modeling real time systems through adding time intervals on the actions is extened. The component-based designs are modeled by a real-time interface automaton network which contains a set of real-time interface automata synchronized by shared actions. Based on analyzing the compatible integer state space of a real-time interface automata network, a corresponding reachability graph is constructed and finally an algorithm for checking the consistency between the real-time component-based designs and the timing scenario-based specifications is developed.
