摘要
软件可靠性模型对于软件可靠性估测起着核心的作用。目前所提出的模型大多有着一定的应用条件和适用范围,不能适应复杂多变的应用环境的要求,在客观上为软件可靠性模型的应用提出了新的问题。提出了一种基于随机Petri网的软件可靠性分析方法,该方法有利于降低可靠性描述与分析的复杂度,提高评价和预测可靠性的精确度。同时指出该方法在应用中会遇到的某些问题及其解决方法。
The software reliability model has the core effect to estimate software reliability. The models suggested at present which have certain application conditions and ranges arc not able to adapt tothe request of complex and volatile application environment mostly. So the application of software reliability model has brought forward the new problem. This paper gives an approach based on stochastic Petri net that can analyzing software reliability. This approach not only is able to reduce the complicated degree of describing and analyzing the software reliability, but also can improve the precision of appraising and forecasting reliability. The paper points out some problems that come across in the application of the method and their solutions at the same time.
