摘要
在完善故障树分析中主要参数最小割集、最小路集、不交化最小割集和不交化最小路集之间相互转化运算的基础上,建立了故障树的定性、定量分析的多种方法,提出了不同结构故障树选择适用方法所应遵循的原则。这些方法和选用原则的合理应用能有效的降低FTA的“NP”困难,为FTA的简化提供了新的途径。
On the base of the perfection of transformation among main data ( minimum cut sets, minimum path sets, non-intersect minimum cut sets, non-intersect minimum path sets) in fault tree analysis, several methods have been biult for the use of fault tree qualitative analysis and quantitative analysis, and rules have been made out to choose the applicable methods for fault trees with different structures. The rational application of these methods and rules can lower the ″NP″ difficulty ,and provide new approach to simplify FTA.
