A New Method for Determining the Objective Weight of Expert in Fuzzy Multi-Attribute Group Decision Making

摘要

In order to get more reasonable weight of expert in fuzzy multi-attribute group decision making, a new method for determining the objective weight of expert is proposed based on the subjective weights. The method simultaneously considers the order difference and the data difference of the alternatives in the decision results between each expert and group, and takes them as the similarity index of measuring the individual and group. At the same time, a new similarity measuring function is defined to determine the objective weight of the experts, in this method, the order difference's existence or not is prior to determine whether the data difference takes part in the calculation. Finally an example shows the feasibility of the proposed method.
