Ordinal Multiattribute Sorting and Ordering in the Presence of Interacting Points of View

In this paper, we use the Choquet integral as a general tool for dealing with ordinal multiattribute sorting and ordering problems in the presence of interacting points of view. The technique that is used proceeds in two steps: a prescoring phase determines for each point of view and for each alternative a net score (number of times a given alternative beats all the other alternatives minus the number of times that this alternative is beaten by the others) and is followed by an aggregation phase that produces a global net score associated to each alternative.
