Generalized Pythagorean fuzzy sets and new decision-making method

Abstract

The thought of the Pythagorean fuzzy soft set emerging from the Pythagorean fuzzy set, which is initiated by Yager, was generalized by including a parameter by Kirisci. In the present communication, a new decision-making method is defined. For this decision-making method, an algorithm is conceived. The reason for giving this algorithm is to facilitate the solution of multi-attribute decision-making difficulties. A numerical example concerning a medical diagnosis problem for the proposed algorithm has been successfully illustrated.
