Multi-criteria group decision support system aims to support preference-based decision over the available alternatives that are characterized by multiple criteria in a group. This research adopts the fuzzy analytic hierarchy process as the analytical tool that determines the weights of each criterion. The fuzzy analytic hierarchy process method is used to determine the weightings for evaluating criteria among decision makers. Vlsekriterijumska Optimizacija I Kompromisno Resenje (VIKOR) is to find out the best solution among these alternatives. Fuzzy theory provides a proper tool to encounter with uncertainties and complex environment. The purpose of this paper is to use the fuzzy AHP and VIKOR method based on fuzzy sets in solving MCDM problems. A practical numerical example is provided to demonstrate the usefulness of this study. The proposed method enables decision analysts to better understand the complete evaluation process and provide a more accurate, effective and systematic decision support tool.
