| 摘 要： | 针对传统RPN(Risk priority number)方法的缺点,提出了以多专家评估为基础的多种评估值表述方式。专家权重用一种客观的权重度量方法来确定。利用基于按对理想解的相似度定序法思想(Technique for order preference by similarity to an ideal solution,TOPSIS)的距离测度对区间RPN值进行排序。应用所提出的方法,对某型号加工中心3个关键部件的各故障模式进行了RPN计算和排序,指出了可靠性薄弱环节,为整机RPN分析提供了方法。

| Abstract: | To overcome the shortcomings of the traditional risk priority number(RPN) method,an evaluation method with multi-assignments was proposed based on the multi-expert evaluation.The expert weight was assigned by an abjective weight measure.The interval RPNs were sorted using the distance measure based on the idea of the technique for order preference by similarity to an ideal solution(TOPSIS).As an example,the RPNs of the fauer modes of 3 critical components of a certain type of machining center were calculate... |
