Abstract:

A method of determining the objective weight of expert based on linguistic set measure theory for linguistic multiple attribute group decision making is proposed. Following three principles as precise better than vague, minority subordinate to majority and distinguishing exactly better than roughly, the method  extracts information  of expert weight from multigranularity linguistic assessment matrix, including the weight of individual assessment information amount, the weight of individual consistency with group and the weight of individual distinguishing capability. The methods of calculating these three weights are given. The total weight is calculated based on these three subweights. The numerical example illustrates the proposed method is feasible and effective.
