一种具有平均累积优势度的排序方法

本文结合特征向量法（EM）及和法（SM）优点，提出了一种新的排序方法一具有平均累积优势度的和法（DSM），同EM，SM，MDM6]相比，此法简单，实用，可靠，计算权重所需时间少，且与EM总量得到相同的方案排序，而其它方法如平均优势度矩阵法（MDM），对数最小二乘法（LISM），最小偏差法（LDM）有时会产生逆序。

A Mean Cumulative Dominance Method for Priorities in AHP

This paper presents a new priority method-the mean cumulative dominance sum method(DSM) with the good characteristics of EM and SM.Compared with the EM,the SM,and the MDM,the DSM is a simple,practical and more rational method and needs less time in calculating the weight vectors of judgement matrices.The results of numerical examples also show that the DSM and the EM always derive the same rankings,but the other methods such as the LDM,the LLSM,and the MDM sometimes are likely to obtain the rankings which differ from those derived by the DSM and the EM.
