Electre Tri is a set of methods designed to sort alternatives evaluated on several criteria into ordered categories. In these methods, are assigned categories by comparing them with reference profiles that represent either the boundary or central elements category. The original Tri-B method uses one limiting profile for separating category from below. A more recent method, Tri-nB, allows use sa...

ELECTRE TRI-nB is a method designed to sort alternatives evaluated on several attributes into ordered categories. It an extension of TRI-B that uses limiting profiles, instead one, delimit each category. In previous paper we have characterized the partitions can be obtained with TRI-nB, using simple axiom called linearity. The simplicity this characterization crucially rests possibility use as ...

In this paper, we present (to the best of our knowledge) first outranking method to assign a score each alternative. This is part Electre family, and will call it Electre-Score. contrast Multi-Attribute Value Theory methods, Electre-Score does not construct value function for criterion proceed then aggregation into single value. Instead, makes use relations make comparison with sets reference a...

This paper presents a new method for multiple criteria ordinal classification (sorting) problems. This type of problem requires the different classes or categories to be pre-defined and ordered, from the best to the worst or from the worst to the best. The actions (not necessarily known a priori) are assigned to the different ordered classes. Several ELECTRE type methods were designed to deal w...

OBJECTIVE The aim of this paper is to apply an informatics tool for dealing with a medical decision aiding problem to help infertile couples to become parents, when using assisted reproduction. METHODS A multiple criteria decision aiding method for sorting or ordinal classification problems, called Electre Tri-C, was chosen in order to assign each couple to an embryo-transfer category. The se...

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...

Trustworthy software evaluation is taken as the multi-criteria decision aiding process in this paper. The use of ELECTRE TRI method for evaluating software trustworthiness is presented. Software under evaluation is compared with some predefined norms and is assigned to one of trust levels. The entire evaluating process is described, including definition of problem situation and formulation, det...

In 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-discordanc...
