Ordinal regression revisited: Multiple criteria ranking using a set of additive value functions
Distinguishing necessary and possible consequences of preference information on the complete set of actions, UTAGMS answers questions of robustness analysis and can support the decision maker when his/her preference statements cannot be represented in terms of an additive value function. Expand
Inferring an ELECTRE TRI Model from Assignment Examples
An interactive approach that infers the parameters of an ELECTRE TRI model from assignment examples is proposed that lies in the possibility given to the DM to revise his/her assignment examples and/or to give additional information before the optimization phase restarts. Expand
A user-oriented implementation of the ELECTRE-TRI method integrating preference elicitation support
This paper presents a new implementation of an existing method called ELECTRE TRI, which integrates specific functionalities supporting the decision maker (DM) in the preference elicitation process and aims at reducing the cognitive effort required from the DM in the phase of calibration of the preference model.

Supporting groups in sorting decisions: Methodology and use of a multi-criteria aggregation/disaggregation DSS
This paper shows how IRIS may be used to help the group to iteratively reach an agreement on how to sort one or a few actions at a time, preserving the consistency of these sorting examples both at the individual level and at the collective level. Expand
Using assignment examples to infer weights for ELECTRE TRI method: Some experimental results
Results showed that this tool is able to infer weights that restores in a stable way the assignment examples and that it was able to identify “inconsistencies” in the assignmentExamples. Expand
Using Assignment Examples to Infer Category Limits for the ELECTRE TRI Method
Given a finite set of alternatives, the sorting (or assignment) problem consists in the assignment of each alternative to one of the predefined categories. In this paper, we are interested inExpand
IRIS: a DSS for multiple criteria sorting problems
Interactive Robustness analysis and parameters' Inference for multicriteria Sorting problems (IRIS), a Decision Support System (DSS) designed to sort actions described by their performances on multiple criteria into an ordered set of categories defined a priori. Expand
Inferring Electre's veto-related parameters from outranking examples
This paper proposes mathematical programs to infer veto-related parameters, first considering only one criterion, then all criteria simultaneously, using the original version of Electre outranking relation and two variants, and shows that these inference procedures lead tolinear programming, 0–1 linear programming, or separable programming problems, depending on the case.

Valued outranking relations in ELECTRE providing manageable disaggregation procedures
It is shown that the modified outranking relation used in the ELECTRE III and ELECTRE TRI makes it easier to solve inference programs, and preserves the original discordance concept. Expand
