Expanding Pythagorean fuzzy sets with distinctive radii: disc Pythagorean fuzzy sets

Abstract This article presents the circular Pythagorean fuzzy set (C-PFS) model, a generalization of intuitionistic model that improves its performance thanks to acclaimed extension sets sets. Then, we generalize C-PFSs produce novel disc (D-PFSs). The constituent elements both and D-PFSs are values, either with common or distinctive radius. We lay out some fundamental algebraic arithmetic operations on (hence C-PFSs), namely union, intersection, addition, multiplication, scalar explore main features these operations. propose investigate properties weighted average/geometric aggregation operators. “COmbinative Distance based ASsesment" approach, which is Hamming Euclidean distances, expanded D-PFS framework. To justify implementability, apply new methodology case study (selection best supermarkets buy fresh fruit for hotel) then compare it related solutions.
