摘要
本文根据ＢＤＤ表示故障树的特点，提出了一种不需由ＢＤＤ树求得割集而直接搜索ＢＤＤ计算部件重要度的方法。就概率重要度而言，利用本方法可使部件的逆概率重要度的计算充分利用正概率重要度计算的中间结果，使得逆概率重要度的计算时间可以忽略不计。
In this paper, a method based on BDD to directly compute Simportance of elments is presented. With this method, we can make full use of the intermediate results evaluating positive probability importance of an element to get the negative probability importance of the same one, which makes the latter process need little time.
