摘要： 可靠性是质量体系中最重要的特性之一，针对构件软件系统，利用相对独立的构件开发与系统开发的特点，从路径分析与基于运行剖面测试的思想出发，建立了分层的系统可靠性模型.模型可根据路径信息的层次和构件信息详细程度，调整到适当的粒度层次.并通过统计测试试验数据给出了模型的实例应用，同时提出了提高可靠性估计准确性的方法.

关键词: 软件可靠性, 层次模型, 路径分析, 运行剖面

Abstract: Reliability is an important characteristic in quality architecture. For a component based software system, based on path analysis and testing from operational profile, a system reliability model is built using characteristics of the component development process and the system development process that are mutually unrelated. According to the layers of path information and the particular degree of component information, the model can be used at the appropriate granularity. An actual model is shown by statistical testing data, and methods for improving accuracy of reliability estimation is proposed.

Key words: software reliability, layered model, path analysis, operational profile
