摘要： 基于构件的软件可靠性分析往往把构件的可靠性当作自身固有不变的属性，忽略了在不同的运行路径下因构件所处的交互环境不同造成的实际可靠性的变化。因此，提出一种改进的基于路径的构件软件可靠性模型，它引入构件动态迁移图来建立构件软件运行路径和构件可靠性关系，给出一种改进的基于路径的用以计算构件软件可靠性的方法。最后通过实例验证了该方法的有效性和可行性。
关键词: 构件软件，软件可靠性，动态迁移图，TE-NHPP
Abstract: Component based software reliability analysis typically takes the reliability of component as an invariable property of component itself , while disregards the fact that it is changed when the component context that it interacts with is changed due to a different route. This paper proposed a improved component based software reliability modelbased on route, which introduces the dynamatic transition graph to build the relationship between the route of component based software and component reliabity, and gave a improved method based on route to caculate the componet based software reliability. At last, the result of case demonstrates the feasibility and validity of the approach.
Key words: Component based software, Software reliability, Dynamatic transition graph, TE-NHPP
