A Common Framework for Describing Most Aggregation Procedures in Decision Making
Thierry Marchant
Many axiomatic results concerning aggregation procedures in decision aiding have been obtained in the
framework of conjoint measurement of social choice theory. We show that these frameworks, although
they helped us to better understand some aggregation procedures, are not totally appropriate for decision
aiding. We propose a new framework, very general, in which most aggregation procedures can fit and
more appropriate for the axiomatization of aggregation procedures in decision aiding context. We present
some axiomatic results obtained in this framework and showing its interest.
