关于Saaty对模糊逻辑不适用于AHP观点的评述

Research review on Saaty's comments on fuzzy logic is not applicable to analytic hierarchy process

目前模糊AHP方法在国内外应用很广泛,但是AHP理论创始人Thomas L.Saaty近几年连出3篇论文质疑模糊AHP方法的科学性.在介绍模糊AHP方法的基础上,从模糊AHP缺乏数理逻辑性、AHP判断本身就来自模糊语义再次模糊意义不大和模糊AHP对不一致性的改进不一定能确保改进结果的有效性等角度对Saaty教授批判模糊AHP方法的观点进行系统阐述,并就经典AHP和模糊AHP两方观点进行了深入的分析,希望对国内决策科学领域的研究学者有一定的启发帮助.

Fuzzy analytic hierarchy process has been widely used in many fields, but Thomas L. Saaty, the architect of AHP, questioned the vMidity of fuzzy AHP and had published three articles which show the invalidity of using fuzziness with the AHP. In this paper, we review Saaty＇s comments on fuzzy AHP from three aspects： fuzzy AHP is lack of mathematical validity; the judgments in AHP are themselves already fuzzy and fuzzy them again has no meaning; improving inconsistency need not improve the validity of the outcome. Through this paper, we do further analysis on both AHP and fuzzy. We hope it will make some help for decision-makers when using AHP.
