摘要
将模糊关系法与故障树分析相结合,先利用专家评判法建立影响因子隶属度关系矩阵,再模糊量化不同矿区的工况条件,与关系矩阵运算得到一个乘因子,故障树底事件平均故障率与该乘因子之积即为当前工况下的故障率,最后代入故障树定量计算出顶事件发生概率。
Combined the fuzzy relation method with the fault tree analysis.Firstly,the expert evaluation method was used to establish the membership relationship matrix of the influence factors.Then the working conditions of different mining areas were fuzzy quantified,and a multiplication factor was obtained by calculating with the relationship matrix.The product of the average failure rate of the event at the bottom of the fault tree and the multiplication factor is the failure rate under the current working condition.Finally,the probability of the top event was quantitatively calculated by substituting the fault tree.
