主观线性加权评价问题的新方法:中位数层次分析法

A New Method for Subjective Linear Weighted Evaluation: the Median Analytic Hierarchy Process

AHP方法是主观线性加权评价的一个代表性方法,但存在标度合理性欠缺、一致性检验缺乏客观依据、引入新评价方案时存在逆序矛盾等三个主要不足。本文提出评价者对指标、方案直接评分,然后使用中位数将不同评价者给出的评分进行信息综合,最终给出指标权重与方案排序。新方法思路清晰简单,消除了AHP方法存在的三个主要不足,应用价值更强。

The AHP method is a representative method of subjective linear weighted evaluation problem,but there are three main shortcomings which are lack of the rationality of the scale,the lack of consistency test objective basis,reverse order contradiction while introducing new evaluation scheme. This paper puts forward a new method which eliminates the three main problems longly existing in AHP method,and the new method has stronger practical value than AHP.
