A Single-Factor Fuzzy Evaluation Method of Using Information Entropy to Determine the Property Weights
Xiaoqi Jiang · Computer Engineering and Science · 2010
In multi-attribute decision-making,because of the complexity of the problem,the weights of attributes are generally unknown or some information of the weights known.How to determine the weights of multi-attribute decision making,sort or evaluate the existing scheme has become a priority issue of multi-attribute decision-making.Up to now,the method to determine the weights of the multi-attribute decision-making includes the subjective and objective methods.The subjective method has the shortcomings of subjective preferences and the objective method tends to ingore the level of the participation of the decision makers.Therefore,how to study the combination of subjective and objective weightes and improve the accuracy of decision-making has practical research significance.This paper summarizes the methods of weight determination in the multi-attribute decision-making,and proposes method of the combination of subjective assignment and objective determination to improve the entropy weight.With an example,the validity of algorithm is proved.
