The interaction operations over Pythagorean fuzzy numbers are defined, including addition, scalar multiplication, multiplication and power operations.Then, the Pythagorean fuzzy interaction weighted averaging (PFIWA) operator, Pythagorean fuzzy interaction ordered weighted averaging(PFIOWA) operator, Pythagorean fuzzy interaction weighted geometric(PFIWG) operator, and Pythagorean fuzzy interaction ordered weighted geometric (PFIOWG) operator are proposed, and the mathematical expressions of these operators are obtained by derivation and some properties of these operators are investigated. A method based on Pythagorean fuzzy interaction aggregation operators for decision making is presented, and an illustrative example is given to illustrate the stability and effectiveness of the proposed method.
