| 摘 要： | 通过分析软件系统的组件结构特征、运行状态和可靠性因素，提出了基于随机Petri试网运行状态的可靠性分析方法。对构成软件系统的各组件的可靠性进行分析和评估，根据系统运行状态动态跟踪软件的可靠性，推导出整个软件系统的可靠性。与仅着眼于系统组件间的执行路径不同，该方法更关注于系统各个运行状态的可靠性。最后给出了一个实例研究。

| Abstract: | Puts forward a reliability analysis method based on Petri net's running state via analyzing the characteristic of the component structure,the running state,and the reliability factor of the software system.First analyze and evaluate the reliability of the elements of the software architecture,then trace the reliability of the system through its running state,and finally deduce the reliability of the whole software.Unlike putting much emphasis on each execution path of the system,focus on its running states.In the end present an example about how to evaluate the reliability of a simple component-based system. |
