Abstract

T-spherical fuzzy sets (T-SFSs) and spherical fuzzy sets (SFSs) are the generalizations of fuzzy sets (FSs), intuitionistic fuzzy set (IFS) and picture fuzzy sets (PFSs). This manuscript is a contribution to the area of SFSs and T-SFSs. In this manuscript, some properties of aggregation operators for SFSs and T-SFSs are discussed and some ordered weighted geometric (OWG) and hybrid geometric (HG) operators are developed. It is discussed that these aggregation operators are generalizations of the aggregation operators of IFSs and PFSs. Multi-attribute decision making (MADM) process is discussed in spherical fuzzy environment and illustrated with a numerical example. The results obtained are compared with the existing structures.
