Generalized hesitant fuzzy prioritized Einstein weighted averaging operator and its application in group decision making

In this paper, a hesitant fuzzy multiple attribute group decision making problem where there exists a prioritization relationship over the attributes and decision makers is studied. First, the generalized hesitant fuzzy prioritized Einstein weighted average operator is proposed. Then, some special cases and their desirable properties are investigated. Furthermore, the procedure of group decision making based on the proposed operators is given under hesitant fuzzy environment. Finally, a practical example is provided to illustrate the developed approach.
