Interval type-2 fuzzy sets contain membership val...

Abstract This article is concerned to delineate the strategic approach of ELiminating Et Choice Translating REality (ELECTRE) method for multi-attribute group decision-making (MAGDM) in terms complex spherical fuzzy sets. The feasible, well-suited, and marvelous structure set compliments efficiency ranking calibre ELECTRE I present a beneficial supreme aptitude strategy MAGDM. Beside proposed m...
