In a group decision-making process, contradictory pairwise comparisons may exist in
individual preferences or the group preferences even though the consensus level is …

Many applications of intuitionistic fuzzy sets depend on ranking or comparing intuitionistic
fuzzy numbers. This paper presents a novel ranking method for intuitionistic fuzzy numbers …

The uncertain group decision-making (UGDM) methodology has developed rapidly in recent
years, which is synchronous with the evolution of fuzzy set (FS) theory and linguistic term set …

Considering the conflicting opinions and different risk attitudes among decision-makers
(DMs) in group decision making (GDM), this paper develops a novel compatibility model …

Uncertain linguistic variables and scoring evaluations are two important evaluation
mechanisms in the decision making field. Sustainability requirements for ship investment …

The intuitionistic fuzzy set has emerged as a powerful technique for presenting evaluations
