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...

The aim of this paper is to convince the MultiCriteria Decision Aid (MCDA) and Preference Learning communities to investigate and to contribute in the development of methodologies dedicated to hospital ranking. To do so, we present the French hospital ranking and show how these rankings can be built properly through two existing methods: decision tree and ELECTRE Tri.

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...
