| 摘 要： | 针对分级分布式软件系统的可靠性,提出了一种评估算法和流程。在确定软件失效判据的基础上给出了可靠性建模方案,采用自下而上的方法,利用模块分析法求解底层软件模块的可靠度,利用层次分析法求解模型中的权重系数,最后求解出整个软件系统的可靠度。通过实例说明了分级分布式软件系统的可靠性评估算法的流程。

| Abstract: | An evaluation algorithim and flow is proposed for hierarchical and distributed software system.Reliability modeling is made based on the definition of software failure criteria.From bottom to top,the reliability of the software module is obtained through modeling method and weight coefficient of models is gained by hierarchical analysis method and finally the reliability of whole software system is obtained.The flow of the reliability evaluation algorithm is validated through simulation example. |
