Pythagorean Triangular Fuzzy Linguistic Hamacher Aggregation Operators and Their Application

Based on the Pythagorean fuzzy set and Hamacher operator, the Pythagorean triangular fuzzy linguistic Hamacher aggregation operators are studied. Firstly, the definition, the operational laws, score function and accuracy function of the Pythagorean triangular fuzzy linguistic set are proposed. Then, a series of Pythagorean triangular fuzzy linguistic Hamacher aggregation operators are developed, such as the Pythagorean triangular fuzzy linguistic Hamacher weighted average (PTrFLHWA) operator and the Pythagorean triangular fuzzy linguistic Hamacher geometric (PTrFLHWG) operator. Moreover, some properties of these operators are discussed in detail. Afterwards, two new approaches to Pythagorean triangular fuzzy linguistic multi-attribute group decision making are presented based on the proposed operators. Finally, a practical example is given to illustrate the effectiveness of the proposed approaches.
