一种新的故障树直接分析法

本文给出一种新的大系统故障树直接分析法,首次提出最小相关子树概念,有效地减少了分析的计算量。作者按此算法编出DFTA程序,用它可求出多种可靠性参数,而且处理问题能力强,运算速度快,占内存极少。这使在微机上分析大系统故障树成为可能。

A NEW DIRECT ANALYSIS METHOD OF FAULT TREES

A new direct method for the large fault tree analysis and a new concept,the minimum relative subtree, have been given in this paper. A computer codeDFTA has been written according to the method, it can compute many reliabi-lity parameters of systems and modules, its speed is fast and the size ofstorages it repuires is very small,this makes it possible to analyize largefault trees with micro-computer.
