AHP中（0，2）EM法与（1／9，9）EM法的比较研究

A Comparative Study Between the(0,2)EM and the(1/9,9)EM of the AHP

本文通过对Ｓａａｔｙ提出的（１／９，９）ＥＭ法与左军提出的（０，２）ＥＭ法的比较研究，认为（０，２）ＥＭ法尚存在三点不足之处：（１）判断信息的损失；（２）累积优势度的损失；（３）一致性的损失。并提出一个判别一种比较标度适应性的指标──随机序隐率。

This paper,by inspection of(0,2)EM and(1/9,9)EM, considers the(0,2)EM has some losses in judgment infoimation,consistency and accumulative superiority,and Puts for-ward a new index-Ratio of the Hidden Order to judge the adaptbility of a scale.
