[en] One basic assumption to consider an additive utility function is the preferential independence. When interacting criteria are considered, this condition might be violated and a substitute to the classical weighted mean has to be adopted. The Choquet integral seems to be an adequate aggregation operator that extends the weighted mean and the ordered weighted average (OWA). The axiomatics that supports the Choquet integral is presented as well as its behavioral analysis with regards to veto and favor effects, degree of disjunction and measure of dispersion. One illustrative example of its application in the field of MCDM is provided.
