Extension of the VIKOR for decision-making problems under fuzzy environment

The multiple attribute decision making (MADM) problem with fuzzy data is investigated in this paper, initiated with a desire to utilize a fuzzy decision making tool in the configuration evaluating of C3I systems in service. In some cases, determining exact values of the attributes are difficult and as result, their values are considered as fuzzy data, which can be described by linguistic values or triangular fuzzy numbers. Therefore, the aim of this paper is to extend the compromise method VIKOR for decision-making problems under fuzzy environment. An algorithm is presented to determine the most preferable choice among all possible choices when data is fuzzy numbers. The procedure of the proposed algorithm is illustrated with a real example.
