摘要
本文描述了Sharp算法的简要原理,编制了用Sharp算法计算系统可靠性指标的程序,该程序的主要特点:(1)输出最小路集、最小割集、故障树顶事件概率及其置信区间,部件的概率重要度和结样重要度;(2)能计算相干系统故障树顶事件概率,也能计算非相干系统故障树顶事件概率;(3)运算速度快,计算机内存少。
In this paper, the fundamentals of the Sharp algorithm are discuss-ed, and a program to calculate the indexes of system reliability by using theSharp algorithm is devoloped. The mojor features of the Sharp program are:(1) it can turn out the minimal path set, the minimal cut set, the probability ofthe fault tree top-event and its confidence bounds, as well as the probabilityimportance and structural importance of the individual components; (2) it cancalculate not only the probability of the fault tree top-event of the coherentsystems but also that of the noncoherent systems; (3) the operation speed isincreased and the requisite capacity of the computer memory can be reduced.
