一种更优的精度控制故障树解算方法

A Better Method Controlled by Accuracy to Resolve a False Tree

本文针对安全分析方法中故障树解算问题提出了一种完全依赖于所要求精度的近似算法——精度取舍法,详细给出了近似求解顶事件概率值的两个截断条件.结论表明,它在同时兼顾精度与时间的要求方面优于别的算法.

In this paper, a approximate algorithm named ACCURACY CONTROLLED METHOD is provided to get the results of a false tree (FT). The algorithm depends on the given accuracy only. Two requirements used to terminate a calculation about top event probability also are given in detailed. As a result, the algorithm is better than other methods in accuracy and time.
