ABSTRACT

By integrating the algebraic aggregation operators and Einstein aggregation operators, an interval-valued pythagorean fuzzy Hamacher weighted averaging operator are proposed. Then, some desirable properties of these operators are considered. Moreover, an illustrative example is provided to demonstrate their practicality and effectiveness of the proposed method.
