Abstract: Generalized orthopair fuzzy hybrid aggregation operator with its application to decision making is considered in this paper. For the advantage that generalized orthopair fuzzy membership space is larger than those of Pythagorean fuzzy sets and intuitionistic fuzzy sets, we combine hybrid aggregation operator and generalized orthopair fuzzy sets. Firstly, the generalized orthopair fuzzy hybrid aggregation operator is defined based on the concepts of generalized orthopair fuzzy sets and the hybrid aggregation operator. Secondly, we examine the properties of the generalized orthopair fuzzy hybrid aggregation operator. Meanwhile, we explain the degenerations of the developed operator under some special conditions. Finally, the application of generalized orthopair fuzzy hybrid aggregation operator in multiple attribute decision making is verified by an example which shows the feasibility and rationality of the proposed method, and the influence of the parameter within the operator on the ranking results is discussed.

Key words: generalized orthopair fuzzy set, hybrid aggregation operator, multiple attribute decision making
