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 ...

A multicriterion methodology is used in the evaluation and selection of the most appropriate alternative(s) for removing algae from stabilisation ponds effluents in a case study in Brasilia. For this purpose, five different natural treatment processes are tested at pilot scale: rock filter, sand filter, floating aquatic plants, constructed wetlands, and overland flow. These pilot units were con...

The selection of students is a complex decision making process, in which multiple selection criteria often need to be considered and where subjectiveness and imprecision are usually present, resulting that fuzzy and imprecise data should be used. This paper formulates the student selection process as a multicriteria decision analysis problem, concretely as a ranking problem, by using the ELECTR...

A rich georeferenced data base on a flood event in the north west of Italy and the knowledge of experts from the different involved disciplines have been used as the basis for the application of an outranking method, ELECTRE III, oriented to the structuring and validation of consistent multicriteria models for hazard evaluation. The models were developed with the aim of explaining the multidime...

A comparative study of ranking river basin planning and development alternatives under a multi-criterion environment, including both qualitative and quantitative aspects using ELECTRE and RANFUW methodologies, is presented in this paper. The purpose is to find the most suitable planning for reservoirs with their associated purposes aimed at the sustained development of one of the major peninsul...

Purpose: This paper presents an algorithm that can elicitate (infer) all or any combination of ELECTRE Tri-B parameters. For example, a decision-maker maintain the values for indifference, preference, and veto thresholds, our find criteria weights, reference profiles, lambda cutting level. Our approach is inspired by Machine Learning ensemble technique, Random Forest, that, we named as Tree alg...

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...
