On the use of the Choquet integral with fuzzy numbers in multiple criteria decision support

摘要

This paper presents a multiple criteria decision support approach in order to build a ranking and suggest a best choice on a set of alternatives. The partial evaluations of the alternatives on the points of view can be fuzzy numbers. The aggregation is performed through the use of a fuzzy extension of the Choquet integral. We detail how to assess the coefficients of the aggregation operator by using alternatives which are well-known to the decision maker, and which originate from his domain of expertise.
