As an important component of group decision making, the hybrid multi-criteria group
decision making (MCGDM) is very complex and interesting in real applications. The purpose …

This chapter develops a new method for solving multiple attribute group decision-making
(MAGDM) problems with Atanassov's interval-valued intuitionistic fuzzy values (AIVIFVs) and …

Pareto-optimal solution that simultaneously maximizes the degree of satisfaction and …

Group decision making (GDM) with interval-valued intuitionistic fuzzy preference relations
(IVIFPRs) is a critical issue in decision analysis field. This chapter proposes a new method …

This paper analyzes the limitations of existing score functions of intuitionistic fuzzy set. A
new score function is defined based on the prospect value function, and examples are given …

Imprecision and vagueness often occur in practical multi-attribute decision making (MADM)
problems. Intuitionistic fuzzy (IF) sets are flexible to simulate these situations. The aim of this …
