摘要
提出一种基于随机Petri网的软件可靠性分析方法。该方法的可靠性模型可以很好地描述软件系统的动态变化过程,并可以得到软件系统处于各个状态的瞬时及稳态概率,为系统运行一定时间后的可靠性情况提供有利的分析手段。此外,所获得的结果也可以直接用于指导后期的开发过程。
In this paper it gives an approach based on stochastic Petri net that can evaluate software reliability. The software reliability model build by this method is able to describe the dynamic change process of software well and to get transient and steady state probability of software system in various states, which provides a powerful means for analyzing the reliability after software has operated for a period of time. Moreover, the evaluated results can be used directly as the guidance of software post-development.
