马尔可夫链的模块化软件可靠性研究

Study on Reliability of Modularized Software based on Markov Chain

针对模块化软件系统,考虑到模块自身的可靠性和模块相互转移调用对其系统重要度的影响。利用马尔可夫预测的基本原理,将马尔可夫链引入到模块化软件可靠性模型建立中,通过建立转移概率矩阵,对软件系统的可靠性进行分析并建立可靠性模型。该模型利用从软件开发过程中收集出的可靠性数据,对模块化软件进行可靠性分析,以此来研究软件系统总体的可靠性。

In allusion to modularization software system, module itself reliability and producing different influence by reason of transfer each other, the paper discusses the conception of Markov forecast. Markov chain is introduced into modularization software reliability modeling. By constructing state transition probability matrix, analyzing and establishing modularization software reliability model. The proposed model utilizes the reliability date collect from software development projects and annlyzes the module reliability to study the whole software.reliability of the system.
