用层次分析法求指标权重的标度方法的探讨

A study of scaling method to obtain index weight by analytic hierarchy process

应用层次分析法求指标权重时 ,构造判断矩阵是最关键的步骤之一。本文论证了用“1～ 9标度法”构造判断矩阵时求出的指标权重与决策者的心理判断存在着偏差 ,并提出了一种实用的“比例标度法”

It is one of the key steps to construct decision matrix when obtaining index weight by hierarchy process. This paper demonstrates that there are some differences between index weight that is obtained through constructing decision matrix by “1 9 scaling method” and the mental judgement of the same decision maker,and moreover,brings forward a practical “proportional scaling method”.
