基于Petri网的构件软件系统可靠性研究

近年来,构件软件系统已成为软件工程领域的研究热点以及大型软件系统与软件产品线进行开发的关键技术之一。对构件软件系统的可靠性分析是进行软件开发的一个重要依据,为了提高软件系统的性能,一个可靠的系统架构是整个软件系统的基础。文章通过分析构件软件系统的特征和可靠性因素,提出了一种基于Petri网的构件软件系统可靠性分析方法,对构件软件系统的各因素的可靠性进行分析评估,从而推导出整个构件软件系统的可靠性,并在开发后期对构件软件系统可靠性进行改进。

Research Reliability of Omponent-Software Based on Petri Net

In recent years, the component-software has become research focus in software engineering domain, and which is the one of the key techniques in developing large software systems and software product line. It is an important basis to proceed to the development of software that analyzes the reliability of component-software. This paper puts forward an component-software reliability analysis method based on Petri net via analyzing the characteristic and reliability factor, and deduces to reliability of whole component-software via analyzing and evaluating each path, finally improve on the reliability of component-software in anaphase.
