摘要

层次分析法是一种进行定量和定性分析相结合的多目标决策分析方法

广泛应用于多特征量权重计算。文中对层次分析法进行改进

利用统计学的相关理论

把系统聚类分析方法和众数理论应用于层次分析法

结合专家所构造判断矩阵的一致性程度

通过加权平均算法得到指标的综合权重排序。改进的层次分析法不仅充分保留了原有判断矩阵的信息

同时全面考虑了专家个体判断结果的准确性和专家组综合意见。将改进的层次分析法应用于2个变压器油纸绝缘状态评估实例

算例结果表明:改进的层次分析法所得权重与传统层次分析法相比

更逼近变压器油纸绝缘状态评估指标的"实际优先次序"。

Abstract

Analytic hierarchy process（AHP） is a multi-objective decision analysis method which ombines quantitative and qualitative analysis.It is widely used in multi-feature weight calculation.In this paper

the AHP is improved by applying the systematic cluster analysis method and the mode theory based on the theory of statistics.Combined with the consistency degree of the judgment matrix constructed by experts

the index comprehensive weight order is obtained by weighted average algorithm.The improved AHP fully retains the information of the original judgment matrix.At the same time

the judgement accuracy of individual expert and the comprehensive opinions of expert group are both taken into consideration.The improved AHP is applied to two transformer oil-paper insulation state evaluation cases.The calculation result shows that the weight obtained by the improved AHP is closer to the actual priority of transformer oil-paper insulation evaluation index compared with the traditional AHP.
