A linguistic fuzzy approach to the consensus reaching in multiple criteria group decision-making problems. (English) Zbl 1366.90120

Summary: The paper introduces a new method of reaching a consensus in multiple criteria group decision-making under fuzziness. This model is based on the general definition of the ‘soft’ consensus introduced by J. Kacprzyk and M. Fedrizzi [Control Cybern. 15, 309–323 (1987; Zbl 0636.90001)]. The fuzzy evaluations of alternatives express degrees of fulfillment of the given goals by the respective alternatives for each expert. The selection of the best alternative is based on the fuzzy consensus by experts. For this purpose a set of alternatives which are good enough with respect to the most of relevant experts is identified. From this set the alternative with the highest center of gravity (defuzzified fuzzy evaluation) is selected as the most promising one.
