Research interests Marc Pirlot Background: Mathematics and Operational Research MCDA (multi-criteria decision aid) Work done or current (central): • Axiomatization of aggregation procedures (max-min, outranking, …) • Study of conjoint measurement models of preference relations • Study of specific partial order structures (e.g. semiorders) as models of preference • Application of MCDA methods in real cases: choice of road pavement and surfacing, choice of cooling system in power plant, …
Less central: • Optimization, metaheuristics • Multiobjective optimization Research interests in connection with Cost Action: Elicitation of preference models • Axiomatized conjoint measurement models (e.g. non-compensatory sorting model of Bouyssou and Marchant) • Theoretical study of optimal exact algorithms for eliciting the parameters of the model (e.g. which coalitions of criteria are sufficient?) • Indirect methods for eliciting (learning) a preference model (e.g. methods based on linear programming like UTA)
Network in Belgium: • MathRO (FPMs, Mons): metaheuristics in multiobjective combinatorial optimization; flexible constraint satisfaction • SMG (ULB, Brussels: Y. De Smet, Ph. Vincke): multi-criteria classification, multi-criteria auctions • Th. Marchant, Dept Data Analysis, UGent (delegate for the Flemish part of Belgium): voting theory, measurement theory • B. De Baets, Dept Applied Math., Biometrics and Process Control, UGent: modelization of imprecision and uncertainty in intelligent knowledge based systems, fuzzy sets, fuzzy preferences
