The Estimation of the Parameters in Multi-Criteria Classification Problem: The Case of the Electre Tri Method

In this work we will address the estimation of the parameters of the well-known Electre Tri method, used to model the ordinal sorting problem. This is a multi-criteria classification problem, in which classes are in the strict preference relation. The parameters are profiles, thresholds, weights, and cutting level; they are linked each other either directly or indirectly with mathematical relations. We propose a new procedure composed of two phases, taking into account that the core of the analysis is the profiles estimation made by linear programming problem
