Workshop Criteria Interactions in Multiple Criteria Decision

June 9, 2017, Brussels (Belgium)

We have the pleasure to invite you to participate in a workshop dedicated to the analysis of criteria interactions in Multiple Criteria Decision models.

In recent years, aggregation procedures involving criteria interactions such as the Choquet and Sugeno integrals or the GAI networks have drawn the attention of many researchers and generated a wealth of contributions. Yet, in practical decision problems, the concept of criteria interactions is not that clear. Beyond the common sense intuition that criteria sometimes can show positive or negative synergies, can we observe clear manifestations of criteria interactions ? Can they be detected by queries to a decision maker formulated in terms of comparisons of alternatives? Is it possible to differentiate the types of interactions at work in the different aggregation models (Choquet, Sugeno, multilinear utility models, …)? Is there a general definition of interaction that could encompass the types of interaction in particular models ? The goal of this workshop is to discuss such questions.
