Interval-valued intuitionistic hesitant fuzzy Quasi-Choquet geometric operators based TOPSIS method for multi-criteria group decision making

摘要

In this paper, we define the interval-valued intuitionistic hesitant fuzzy Quasi-Choquet geometric (IVIHFQCG) operators, then some desirable properties are proposed. Then we show the family of IVIHFQCG operators. Further, the compromise ratio method, the extended Euclidean distance and the extended technique for order preference by similarity to ideal solution (TOPSIS) method are used for these interval-valued intuitionistic hesitant multi-criteria group decision making (MCGDM) problems. A numerical example is given by using the operators of tmakinghe IVIHFQCG family.
