Abstract(s) :

(Anglais) Environmental evaluation often requires to aggregate several indicators of ecosystem services in a single criterion which reflects the overall environmental value. Such aggregation models are generally described by rules provided by experts. In case these rules are many, there is an advantage at summarizing them in a more compact formulation. The noncompensatory sorting model (Bouyssou-Marchant, 2007) is such a compact formulation, which is based on a majority rule and the absence of veto (in the spirit of outranking methods such as ELECTRE TRI, Roy-Bouyssou, 1993). We illustrate this idea on a real environmental assessment project and we examine, in general, the conditions on sets of rules which allow to synthesize them by this model.
