Abstract

This paper studies the problems of fuzzy multi-attribute group decision making in which the attribute values are given in the form of linguistic fuzzy numbers, and presents a new fuzzy group decision making method. Firstly, some definitions and conclusions about trapezoidal fuzzy numbers are given. Secondly, an operator named TOWA is presented to aggregate the trapezoidal fuzzy numbers. Thirdly, a new method is presented for the problems of fuzzy multi-attribute group decision making via the TOWA operator and grey relative degree. Finally, this new method is applied in the problem of official evaluation and selection. Therefore, a feasible and effective way is obtained to solve the problems of fuzzy multi-attribute group decision making under the uncertain environments.
