| 摘 要： | 针对故障树分析结果,根据Fussel-Vesely重要度值在0.5附近的基本事件优先考察的原则,区分最小割集,并对它们进行失效影响概率排序.应用该方法可有效地反映各最小割集引起顶事件发生的可能性大小,达到指导故障隔离、修复,提高诊断速度和诊断效率的目的.

| Abstract: | In this paper, the minimum cut sets obtained from fault tree analysis are distinguished and ranked by failure influencing probability in terms of the principle thatthe basic event with its Fussel-Vesely importance nearest to 0.5 could be inspectedfirstly. This method can the occurrence possibility of the top event resulted fromeach minimum cut set, thus, the fault isolation and repair can be achieved so toimprove the diagnostic rate and efficiency. |
