This paper is devoted to the study of methods allowing to sort multi-attributed alternatives between several ordered categories. Within a general framework that encompasses most sorting models proposed in the literature, we provide an axiomatic analysis of what we call noncompensatory sorting models, with or without veto effects. These models contain the pessimistic version of ELECTRE TRI as a ...

This work proposes a Progressive Assisted Sorting Algorithm (PASA) based on a multicriteria evaluation ELECTRE-type method. The purpose of the PASA is to aid a decision maker to progressively sort a set of alternatives into a set of categories, which we considered are ordered (ordinal sorting), following a consistency principle. We consider the principle that if an alternative outranks (is as g...

Given a ®nite set of alternatives A, the sorting (or assignment) problem consists in the assignment of each alternative to one of the pre-de®ned categories. In this paper, we are interested in multiple criteria sorting problems and, more precisely, in the existing method ELECTRE TRI. This method requires the elicitation of preferential parameters (weights, thresholds, category limits,. . .) in ...
