Supporting groups in sorting decisions: Methodology and use of a multi-criteria...
Damart, Sébastien; Dias, Luís C.; Mousseau, VincentThis paper addresses the situation where a group wishes to cooperatively develop a common multicriteria evaluation model to sort actions (projects, candidates) into classes. It is based on an aggregation/disaggregation approach for the ELECTRE TRI method, implemented on the Decision Support System IRIS. We provide a methodology in which the group discusses how to sort some exemplary actions (possibly fictitious...
Dealing with inconsistent judgments in multiple criteria sorting models
Mousseau, Vincent; Dias, Luís; Figueira, JoséAbstract. Sorting models consist in assigning alternatives evaluated on several criteria to ordered categories. To implement such models it is necessary to set the values of the preference parameters used in the model. Rather than fixing the values of these parameters directly, a usual approach is to infer these values from assignment examples provided by the decision maker (DM), i.e., alternatives for which (...
Valued outranking relations in ELECTRE providing manageable disaggregation proc...
Mousseau, Vincent; Dias, LuísIn ELECTRE methods, the construction of an outranking relation amounts at validating or invalidating, for any pair of alternatives (a,b), the assertion "a is at least as good as b". This comparison is grounded on the evaluation vectors of both alternatives, and on additional information concerning the decision maker's preferences, accounting for two conditions: concordance and non-discordance. ; http://www.s...

IRIS: a DSS for multiple criteria sorting problems
Dias, Luís C.; Mousseau, VincentThis paper presents Interactive Robustness analysis and parameters' Inference for multicriteria Sorting problems (IRIS), a Decision Support System (DSS) designed to sort actions (projects, candidates, alternatives, clients, etc.) described by their performances on multiple criteria into an ordered set of categories defined a priori. It is based on the ELECTRE TRI sorting method, but does not require the decisio...
