不确定综合评价法在机械设备维修决策中的应用

Application of Uncertainty Comprehensive Evaluation in the Decision-making Machinery and Equipment Maintenance

由于在机械设备维修过程中维修策略决策难,决策过程中影响因素不确定,提出将不确定三角模糊数综合评价法应用于机械设备维修策略中,建立机械设备维修决策模型,通过计算模糊评价值的期望值进而得出模糊判断矩阵的权重,并进行总排序以确定机械设备的维修方式,最后通过实例证明,此方法能有效解决机械设备维修策略的决策问题。

For the questions of decision‐making difficult and the factors ,uncertainty in the process of mechanical equipment main‐tenance ,it proposes putting the method of uncertainty triangular fuzzy number comprehensive evaluation in decision‐making of maintenance strategy for mechanical equipment ,and then set up the structure model of fuzzy analytic hierarchy process for me‐chanical equipment maintenance decision‐making ,the weights of fuzzy judgment matrix are obtained by calculating the expectation of the fuzzy evaluation ,and then establish the maintenance strategy of mechanical equipment after the total order ,final ,it proves with the example that the method of analytic hierarchy process based on triangular fuzzy number can effectively resolve the deci‐sion‐making of maintenance strategy for mechanical equipment .
