摘要
故障树分析法在运用过程中容易产生"维数爆炸"等问题,本文重点研究基于BDD算法的故障树分析法,分析故障树转化为BDD的方法,并基于BDD算法求解顶事件发生的概率以及底事件的结构重要度,最后采用该算法进行算例分析与应用。
The process of applying fault tree analysis easily lead to "dimension explosion" and other issues. The BDD-based algorithm of fault tree analysis is studied in the paper, and the method of transformation from fault tree to BDD is analyzed. The top event probability and structural importance of the end of the event based on BDD algorithm is solved. Finally using this algorithm analyze and apply to example.
