摘要：

         现有软件系统可靠性的评估未考虑各功能的执行概率和部件失效严重性等级对软件可靠性的影响. 该文提出根据软件体系结构的软件可靠性评估方法. 用统计方法分析UML描述的软件体系结构，得到各功能的执行概率，并定义了构件和连接件的可靠性. 根据专家经验给出构件和连接件失效的严重性等级，通过场景构建Markov多构件软件系统转换模型，得出软件系统和各构件的可靠性. 以一个ATM系统实例验证了方法的有效性.

Abstract:

   Current software reliability evaluation methods do not take into account the execution probability of each function and the degree of failure severity. We propose a new method for evaluating software reliability based on the software architecture. The UML-described software architecture is analyzed. Execution probability of the functions is derived, and reliability of components and connectors defined. The degree of failure severity of components and connectors are obtained according to expert experiences. A Markov model is constructed from various scenarios, and reliability of individual components and the overall system estimated using the model.  Validity of the method is shown with an ATM example.
