Multi-criteria group decision making method based on generalized intuitionistic trapezoidal fuzzy prioritized aggregation operators

In this paper, we investigate the intuitionistic trapezoidal fuzzy multi-criteria group decision making problems in which decision criteria and the decision makers are in different priority levels. Motivated by the idea of generalized aggregation operators and prioritized aggregation operators, we propose some new prioritized aggregation operator called generalized intuitionistic trapezoidal fuzzy prioritized weighted average operator and generalized intuitionistic trapezoidal fuzzy prioritized weighted geometric operator. Then some desired properties of the new aggregation operators are studied and their special cases are also examined. Further, we apply the proposed operators to construct an approach for multi-criteria group decision making under intuitionistic trapezoidal fuzzy environment. Finally, a practical study on introduction of talents is carried out to verify the developed methods.
