Hesitant fuzzy Hamacher aggregation operators for multicriteria decision making
We research a series of new aggregation operators based on Hamacher t-norm and t-conorm for hesitant fuzzy information. Some Hamacher operational rules of hesitant fuzzy sets are developed. A wide range of new hesitant fuzzy aggregation operators is proposed. We investigate their desirable properties and discuss the relationships between them. The proposed aggregation operators have more flexible for multicriteria decision making under hesitant fuzzy information environment.
