Public procurement contracts are awarded by tendering procedures to the most advantageous candidates. In this paper we propose multiple criteria decision making method for selecting successful contractor. The proposed formalism involves rating and ranking of the alternatives. Decision makers express the ratings of the alternatives with respect to various criteria using linguistic variables, represented with triangular fuzzy numbers. Fuzzy preference matrix is constructed by calculating the difference of evaluation values for each pair of alternatives. We created an application for selecting successful contractor based on the proposed elicitation and ranking techniques in a fuzzy environment
