Principals of Spherical Fuzzy Sets
The 3D extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS). Pythagorean fuzzy sets (PFS). and neutrosophic sets (NS) aim to de scribe experts' judgments more informatively and explicitly. Introduction ...
From 1D to 3D Membership:Sphericalfuzzy Sets
All the extensions of ordinary fuzzy sets with three dimensional membership functions such as intuitionistic fuzzy sets (IFS), Pythagorean fuzzy sets (PFS), and neutrosophic fuzzy sets (NFS) aim at defining the judgments ...
