As a generalization of the Fermatean fuzzy set, the theory of interval-valued Fermatean fuzzy
set (IVFFS) is a more robust and reliable tool to address the imprecise and incomplete …

Uncertainty is often occurred in real‐life decision‐making problems due to the lack of
complete information, imprecise data, and the vagueness of decision making experts in …

Fermatean fuzzy set (FFS) is a more efficient, flexible, and generalized model to deal with
uncertainty, as compared to intuitionistic and Pythagorean fuzzy models. This research …

The treatment of municipal solid waste (MSW) has become an urgently important task of
many countries. This objective of this study is to present a novel group multi-attribute …

The VIKOR model has been considered a viable tool for many decision-making applications
