| 摘 要： | 针对最低设备清单(minimum equipment list,MEL)故障树模型的特点,提出了一种最小割集(mini-mal cut sets,MCS)的求解算法。该算法基于二元决策图(binary decision diagram,BDD)技术,利用改进的多态运算法则和MCS或门求解法则,有效地解决了MEL故障树模型MCS求解过程中的多态部件和重复事件难题。给出了应用该方法的具体步骤,通过算例说明了该算法的有效性。

| Abstract: | To calculate the fault tree's minimal cut sets(MCS) of the minimum equipment list(MEL),a method is brought forward.Based on the binary decision diagram(BDD),both the multistage equipments and the repeated events in the fault tree of MEL are well solved by using the multistate dependent operations(MDO) and MCSOR operation.Finally,this method's application steps are presented,and an example is gived. |
