中文摘要：
在复杂的实时软件系统中使用构件式设计方法，已成为目前软件工程中的研究热点．如何有效地验证实时软件的设计是否满足给定的时间规约，是实时计算领域中的主要挑战之一．通过在接口自动机模型中添加时间区间标记，来扩展其对实时系统接口行为的表达能力；使用实时接口自动机网络柬描述实时软件系统的构件式设计模型；使用带布尔不等式时间约束的UML顺序图表示基于场景的需求规约，对系统设计阶段实时软件构件的动态行为进行形式化分析与检验．通过对实时接口自动机网络状态空间的分析，构造了其可兼容的整型状态等价类空间的可迭图，并在此基础上给出了验证算法，以检验构件式实时软件系统的设计与带时间约束的场景式规约之间的一致性，
英文摘要：
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.
