A multi-criteria group decision making procedure using interval-valued intuitionistic fuzzy sets

This paper presents a decision procedure based on an interval-valued intuitionistic fuzzy Choquet integral operator and TOPSIS method for effectively aggregating intuitionistic fuzzy information in solving multi-criteria group decision making problems in which all the decision information is represented by interval-valued intuitionistic fuzzy values. An example is given for demonstrating the applicability of the proposed decision procedure for solving the multi-criteria group decision making problem. The result shows that the proposed decision procedure is practical and effective for solving the multi-criteria group decision making problem.
