This paper presents Electre Tri-nC, a new sorting method which takes into account several reference actions for characterizing each category. This new method gives a particular freedom to the decision maker in the co-construction decision aiding process with the analyst to characterize the set of categories, while there is no constraint for introducing only one reference action as typical of ea...

Over the last three decades a large body of research in the field of ELECTRE family methods appeared. This research has been conducted by several researchers mainly in Europe. The purpose of this chapter is to present a survey of the ELECTRE methods since their first appearance in mid-sixties, when ELECTRE I was proposed by Bernard Roy and his colleagues at SEMA consultancy company. The chapter...

In this paper, we propose a hybrid fuzzy decision making approach, combining elements of fuzzy-ELECTRE and Fuzzy-TOPSIS, towards a new ranking procedure. The main objective of FETOPSIS is to offer rankings with good alternative discriminatory power to decision makers (DMs). This research work was motivated by a real case study in which multiple attribute decision making techniques were used to ...

Given a finite set of alternatives, the sorting (or assignment) problem consists in the assignment of each alternative to one of the pre-defined 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 (importance coefficients, thresholds, profiles,....

This paper proposes a multicriteria model for assessing public bus operation systems based on the ELECTRE method in the city of Eskisehir, Turkey. In this specific problem, public and expert opinions towards the privatization of urban bus lines were collected through a comprehensive survey to determine the best operation system; either by the local authority or private operators. The data colle...

A modified version of the multi-criteria decision aid, ELECTRE III has been developed to account for uncertainty in criteria weightings and threshold values. The new procedure, called ELECTRE-SS, modifies the exploitation phase in ELECTRE III, through a new definition of the pre-order and the introduction of a ranking index (RI). The new approach accommodates cases where incomplete or uncertain...

The aim of this research is to propose an improved multidimensional quality life index, which could replace the current methodology designed by Eurostat and applied national statistical institutes European Union member states. novelty proposed index that it based on a non-compensatory multicriteria decision method (ELECTRE III). All other indices compensatory aggregation methods at some stage i...

Multiple Criteria Sorting Problem consists in assigning a set of alternatives A"Ma 1 , a 2 ,2, l evaluated on n criteria g 1 , g 2 ,2, n to one of the categories which are pre-de"ned by some norms corresponding to vectors of scores on particular criteria, called pro"les, either separating the categories or playing the role of central reference objects in the categories. The assignment of an alt...

ELECTRE TRI is a set of methods designed to sort alternatives evaluated on several criteria into ordered categories. The original method uses limiting profiles. A recently introduced method uses central profiles. We study the relations between these two methods. We do so by investigating if an ordered partition obtained with one method can also be obtained with the other method, after a suitabl...

Main decision-making problems can be described into choice, ranking or sorting of a set of alternatives or solutions. The principle of Electre TRI (ET) method is to sort alternatives ai according to criteria g j into categories Ch whose lower and upper limits are respectively bh and bh+1. The sorting procedure is based on the evaluations of outranking relations based firstly on calculation of p...
