故障树分析软件研究

Software for fault tree analysis

介绍了故障树分析软件系统 (faulttreeanalysissoftwaresystem ,简称FATS)的总体结构、功能及其实现 .FTAS以图形方式建立故障树 ,供用户选择 .通过对FTAS作定性分析得系统的最小割集 ,用定量分析得失效率、基本事件的三个重要度 .FTAS可考虑多因素影响 ;它可处理各种类型的故障树 ,而且运行速度快 .

Presents the overall structure, function and implementation of fault tree analysis software system (FTAS), which creates the fault trees in the graphic way for users to choose from analyses. Minimum cut sets can be obtained through qualitative analysis run with FTAS, probabilities of failure and three degrees of importance for basic events can be obtained through quantitative analysis run with FTAS. FTAS can take many factors into consideration and processes, it can deal with different sorts of fault trees at high speed.
