Abstract: Component-based software was considered as Markov process. To attach more attention to the reliability of links and become fit to different Markov process states, different state components and link use frequency computing models were proposed. Then, the calculation method for reliability of component-based software was presented, and an example was also given. Compared with traditional methods, the proposed method not only provides a more accurate analysis method for the reliability of software, but also widened the application of the model.

Key words: component-based software, reliability, software reliability

摘要： 把基于构件的软件看作是一个Markov过程,为弥补以往忽视连接件作用的情况，针对过程中不同状态类型,构建出基于不同状态的构件和连接件使用频率计算模型。在此基础上,提出了整个基于构件的软件可靠性计算方法,并将其实例化。与传统的方法相比,该方法不仅提供了一种更精确分析软件可靠性的方法,而且拓宽了模型的应用范围。
