摘要

A method of constructing a group decision matrix based on OWA operator is proposed for the construction method of the group decision matrix research. In this method, the OWA operator is used to aggregate the expert's decision matrix into the initial group decision matrix, then the degree of deviation from the expert's decision matrix and the group decision matrix is obtained base on distance measure so as to determine the weights of experts, finally, the group decision matrix is obtained by the weighted arithmetic average operator. Numerical results show that the quality of group decision matrix constructed by method of this paper is relatively high, compared to the decision matrix constructed by usual method of arithmetic mean, geometric mean and OWA operator.
