AHP中排序权值的修正问题

THE PROBLEM FOR MODIFYING THE WEIGHT VALUES IN THE AHP METHOD

本文对AHP排序权值的产生过程作了浅析;为提高排序权值的准确性提出了排序元素中关键元素对的概念,并根据实验心理学及非线性排序的原理和方法,推导了用关键元素对的有关信息对AHP排序权值进行修正计算的两种方法——幂修正法和乘子修正法。本文还给出了作者为检验两种修正算法而作的一些心理实验的数据,其结果证明,经修正算法修正后的排序权值都非常接近实际值,因此两种修正算法都是有效的和可行的。

This paper analyzes the process of generating the weight values in AHP. ln order to raise the accuracy of weight values, the concept of key pair of elements is put forward, and according to the information given by key pair of elements two methods for modifying the weight values… the power modifiaation method and the multiplier modification method, are given. Also some psychological experiments were carried out for the purpose of verifying two modification methds, as a result of the experiments the weight values modified by these two methods are quite near to the actual weight values. So these two methods are valid and feasible。
