摘　　要：本文从场景的角度研究软件早期可靠性建模方法,给出了基于用例图确定场景运行剖面的方法,利用简化通信图确定可靠性模型中的参数。模型与UML图无缝集成,可应用于软件开发生命周期早期。用个人登录控制系统(PACS)实例介绍了模型的应用。与已有方法相比,该模型简单且容易工具实现。This paper proposes a scenario-based early reliability prediction model. The operation profile of scenarios is built based on the use case diagram. A simple communication diagram is used to get the parameters of the model. This model is integrated seamlessly with UML diagrams, and is applicable early in the software development lifecycle. We demonstrate the application in a case study of an automated personnel access control system. Compared with the previous early reliability models, this model is more simple and easier to be implemented.
