摘要:

层次分析法一定程度受到主观因素影响,该文综合层次分析法与三角模糊数方法提出一种基于模糊层次分析的相控阵无损检测仪器可靠性分配方法。通过引入模糊参数降低可靠性分配决策过程的主观性,以熵最小原则作为参数选择依据,使方法能够更充分、客观、综合地反映专家意见。应用表明,相控阵无损检测仪器主机可靠性分配结果有效、可行,具有一定的工程应用价值。

Abstract: As the analytic hierarchy process (AHP) is affected by subjective factors, a new method for reliability allocation of phased array nondestructive testing instruments based on fuzzy analytic hierarchy process is proposed, using AHP and triangular fuzzy numbers. The subjectivity of reliability allocation decision process is reduced by introducing fuzzy parameters. The parameters are selected based on the principle of minimum entropy, which makes the method reflect expert opinions more fully, objectively and comprehensively. The application results show that the reliability allocation result of the phased array nondestructive testing instrument motherboard is effective and feasible, and has engineering application value.
Keywords: reliability allocation;analytic hierarchy process (AHP);triangular fuzzy number;nondestructive testing instrument
