| 摘 要： | 针对不同类型隶属函数的模糊概率耦合计算的模糊故障树分析瓶颈问题尚未解决,提出了一种新的离散化方法,该算法通过先分割概率后规划隶属度的方式将模糊概率的隶属函数离散化,并由扩展原理修正与、或门模糊算子得到一组新的模糊算子,用新算子进行模糊故障树实例分析表明,新方法不但较好地解决了上述难点,并具有一定理论和工程实践价值。

| Abstract: | To solve the problem of calculation between different membership function of fuzzy probability,a new method of discretization is presented.Membership function of fuzzy probability is discretized by this method.Based on Extension principle,fuzzy arithmetic operator of AND and OR-gates was improved and fuzz fault tree was analysed.The example indicates that the result is satisfactory and the new method is valuable for theory study and engineering application. |
