Abstract
ELECTRE I, IS and its variants are well-known methods to help Decision Makers (DMs) choose one action (alternative) from a discrete set. Here, we consider the case where the DMs have difficulties in fixing precise values for all the parameters required by ELECTRE, such as the importance of the criteria, the veto thresholds or the performances of the actions. We indicate how to obtain robust conclusions when the DMs specify a set of multiple acceptable combinations of values for the parameters. We argue that robust conclusions should be studied at the outranking relation level, and then suggest some approaches to enrich such conclusions (introducing a tolerance) and to exploit them.
