On a sorting procedure in the presence of qualitative interacting points of view

We present a sorting procedure for the assignment of alternatives to graded classes. The available information is given by partial evaluations of the alternatives on ordinal scales representing interacting points of view and a subset of prototypic alternatives whose assignment is imposed beforehand. The partial evaluations of each alternative are embedded in a common interval scale by means of commensurateness mappings, which in turn are aggregated by the discrete Choquet integral. The behavioral properties of this Choquet integral are then measured through importance and interaction indices. The second part of the present paper is devoted to the freeware Tomaso constructed from this particular sorting procedure. We illustrate it by an example, and do some testing in order to show its usefulness.
