Exploitation of a bipolar-valued outranking relation for the choice of k best alternatives
نویسنده
چکیده
This article presents the problem of the selection of k best alternatives in the context of multiple criteria decision aid. We situate ourselves in the context of pairwise comparisons of alternatives and the underlying bipolar-valued outranking digraph. We present three formulations for the best k-choice problem and detail how to solve two of them directly on the outranking digraph. Mots-Clefs. best k-choice decision problem, multiple criteria decision aid, bipolar-valued outranking relation.

R UBIS : a bipolar-valued outranking method for the choice problem
The main concern of this article is to present and motivate the Rubis method for tackling the choice problem in the context of multiple criteria decision aiding. Its genuine purpose is to help a decision maker to determine a single best decision alternative. Methodologically we focus on pairwise comparisons of these alternatives which lead to the concept of bipolar-valued outranking digraph. Th...
متن کاملDisaggregation of Bipolar-Valued Outranking Relations
In this article, we tackle the problem of exploring the structure of the data which is underlying a bipolar-valued outranking relation. More precisely, we show how the performances of alternatives and weights related to criteria can be determined from three different formulations of the bipolar-valued outranking relations, which are given beforehand.
متن کاملRuBy : a bipolar-valued outranking method for the best choice decision problem
The main concern of this article is a detailed presentation of the RuBy methodology for the best choice problem in the context of multiple criteria decision aid. We focus more particularly on pairwise comparisons of decision objects which lead to the concept of bipolar-valued outranking digraph. The work is centred around a list of five pragmatic principles which are required in the context of ...
متن کاملThe integration of valued outranking relations in ELECTRE methods for ranking problem
The ELECTRE family of decision aid methods are well-known approaches in the field of multiple criteria decision aiding (MCDA). Different ELECTRE methods can be used for choice problem, ranking problem and sorting problem respectively. These methods are characterized by outranking relations and exploitation procedures. Different definitions of the outranking relations result in the difference of...
متن کاملPairwise support maximization methods to exploit valued outranking relations in ranking problems
Many outranking methods involve two steps. First, the alternatives are compared pairwise to build a valued outranking relation; this relation is then exploited to derive a recommendation for the decision maker. We present three related exploitation models providing three types of solutions, depending on the decision maker’s request: a linear order, a weak order, or a weak partial order. Each so...
