Interval-valued Pythagorean fuzzy interaction aggregation operators and their application in multiple attribute decision making

摘要

In this paper, the interaction operation laws have been defined between interval-valued Pythagorean fuzzy set. Based on the new operation laws, some aggregation operators have been defined including the interval-valued Pythagorean fuzzy weighted averaging operator and the generalized interval-valued Pythagorean fuzzy weighted averaging operator. A new multiple attribute decision making method has been proposed based on the new aggregation operators. Numerical example has been presented to illustrate the new algorithm.
