Extending choquet integrals for aggregation of ordinal values

In this paper we study the extension of Choquet integrals to ordinal scales. We show that two different integrals can be defined on the basis of two different but equivalent expressions in the numerical case. We prove some properties of the Choquet integrals and show their application to aggregation.The authors acknowledge partial support of the CYCIT project SMASH (TIC96-1138-C04-01/04)Peer Reviewe
