Characterization of some aggregation functions arising from MCDM problems

peer reviewedWe investigate the aggregation phase of multicriteria decision making procedures. Characterizations of some classes of nonconventional aggregation operators are established. The first class consists of the ordered weighted averaging operators (OWA) introduced by Yager. The second class corresponds to the weighted maximum de¯ned by Dubois and Prade. The dual class (weighted minimum) and some ordered versions are also characterized. Results are obtained via solutions of functional equations
