    • From 1D to 3D Membership:Sphericalfuzzy Sets 

      Kutlu Gündoğdu, Fatma; Kahraman, Cengiz (2019-09)
      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 ...
