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. 软件可靠性指标分配 故障树分析法 最小割集 故障树快速分配模型 software reliability allocation fault tree analysis fault tree based fast allocation model minimal cut set TP31.5 国防科技预研跨行业基金 1999-05-01 2021-04-01 5
