In this study, an improved score function of interval-valued intuitionistic fuzzy sets (IVIFSs) have proposed. Based on this, an intuitionistic fuzzy VIKOR (Vlse Kriterijumska Optimizacija Kompromisno Resenje) method has been presented. The fuzzy decision matrices have formed in the form of interval-valued intuitionistic fuzzy sets. Using the proposed score function, group utility and individual regret have computed and hence the compromise solution is determined. One example has been constructed to demonstrate the proposed approach.
