The first part of the lecture is an introduction to Multiple-Criteria Decision Aiding methodology. It starts with from an observation that the dominance relation established in the set of alternatives evaluated on multiple attributes (voters, or criteria, or states of the nature) is the only objective information that stems from the formulation of a multiple attribute decision problem (ordinal classification, or ranking, or choice – with multiobjective optimization being a particular case). While it permits to eliminate many irrelevant (i.e., dominated) alternatives, it leaves many alternatives incomparable. This situation may be addressed by taking into account preferences of the DM. Therefore, decision aiding methods require some preference information exhibiting a value system of a single or multiple DMs.
The second part of the lecture consists in presentation of an MCDA method based on outranking relation preference model, called ELECTRE III/IV. The preference information used to build the outranking relation in the set of alternatives is characterized first, and then exploitation procedures of this relation, leading to a final recommendation, are described. The method is illustrated with a didactic example of a multiple-criteria decision problem. The ELECTRE on Excel software demo will end the lecture.
