A novel spherical fuzzy analytic hierarchy process and its renewable energy application
(2020-03-01)
The extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets, Pythagorean fuzzy sets, and neutrosophic sets, whose membership functions are based on three dimensions, aim at collecting experts’ judgments more ...
A novel VIKOR method using spherical fuzzy sets and its application to warehouse site selection
(2019)
The extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS), Pythagorean fuzzy sets (PFS), and neutrosophic sets (NS), whose membership functions are based on three dimensions, aim at collecting experts' ...
A novel fuzzy TOPSIS method using emerging interval-valued spherical fuzzy sets
(2019-06-03)
All the extensions of ordinary fuzzy sets with three-dimensional membership functions such as intuitionistic fuzzy sets, second type intuitionistic fuzzy sets (or Pythagorean fuzzy sets) and neutrosophic sets aim at defining ...
Extension of WASPAS with spherical fuzzy sets
(2019)
The 3D extensions of ordinary fuzzy sets such as intuitionistic fuzzy sets (IFS), Pythagorean fuzzy sets (PFS), and neutrosophic sets (NS) aim to describe experts’ judgments more informatively and explicitly. In this paper, ...
