Fuzzy programming of group multi-criteria decision making method based on PROMETHEE

Aiming at group multi-criteria decision making with fuzzy evaluation and incomplete information of criteria's weight and decision-maker' weights, the preference functions within PROMETHEE method is expanded embarking on the degree size between every pairs of alternatives. Fuzzy programming optimizing models are constructed to integrate the multi-criteria under single decision-maker and the group decision-makers' preference and the whole attitude to risk. The ranking of the whole alternatives is obtained. The example reveales that the group multi-criteria decision making method is available and the obtained conclusion is creditable.
