摘要
首先对目前已有的各种分配技术与方法的特点进行了探讨，介绍了如何采用故障树技术求得导致系统失效的功能模块的最小割集，首次提出将故障树技术运用到可靠性的分配中，创建了可靠性分配的故障树快速分配模型并具体分析了其在软件可靠性指标分配中的应用． 最后，分析了这种技术的不足，并对该方法可能的改进进行了一些探讨．
The existing methods of software reliability allocation is discussed, The fault tree analysis and its applications for software reliability allocation are introduced. A new fault tree based fast allocation model was established, its application in the software reliability allocation concretely were analyzed. Finally, the deficiency of this method and its probable improvement were discussed.
