一种基于改进型模糊层次分析法的装备维修策略

Equipment Maintenance Strategy Based on Improved Fuzzy AHP

针对层次分析法(Analytic Hierarchy Process,AHP)在确定权重方面存在的不足,引入三角模糊数(Triangular Fuzzy Number,TFN)以确定权重,建立新的层次分析法模型,并以实例进行了验证。通过与标准层次分析法进行比较的结果表明,改进后的层次分析法能处理决策者不确定或模糊的判断,但子元素较多时计算量大,还有待进一步优化。

Aiming at the shortcomings of Analytic Hierarchy Process （AHP） when ascertaining the weighting, use the Triangular Fuzzy Number （TEN） to ascertaining the weighting. Established the new AHP model and validate the model by example. Compared the model with the standard AHP model, The results show that the improved AHP can deal with the uncertainty or fuzzy judgment, but there is more computation when there is a large number of sub element. The optimization is needed.
