| 摘 要： | 本文第一部分提出一类识别生命线系统可靠路径与失效路径的新方法，该方法从系统发生概率最大的可靠路径出发，采用递推分解的思路，识别出系统的互斥可靠路径和互斥失效路径，并给出系统失效概率的表达式和失效概率上下界表达式。实例分析表明，该识别方法的计算复杂性较小并具有较高的运算效率。

| Abstract: | This paper presents a new method to identify key reliable-paths and failed - paths of a lifeline system due to a single random variable. Through the most probability reliability-path, the method recursively decomposes the system and identifies the key disjoint reliable-paths and the key disjoint failure-paths, and gives failure probability bound expression with upper probability and lower probability. It appears that the method is efficient with less computational complexity, as shown in the example. |
