指数标度与1-9标度互不相容及其比较研究

Exponential Scale Not Being Consistent With 1-9 Scale

标度的选择直接影响到应用层次分析法的正确性,本文对最常用的两个标度指数标度与1-9标度作了全面的比较分析,证明了这两个标度的不相容性,得出1-9标度可能导致决策结果错误,而指数标度则是一个优良的结果可靠的标度这一结论。

Choice of scale has direct impact on correctness of the application of AHP. In this paper, exponential scale and 1-9 scale, which are widely used in AHP, are roundly compared and analyzed, and the their inconsistent are proved. As a result of the paper, use of 1-9 scale may induce wrong of decision-making meanwhile exponential scale is a good scale which has many good feature and can induce credible ranking of weights.
