Circular Representations of a Valued Preference Matrix

摘要

In this paper we propose a model for the graphical representation of valued preference matrices. These are obtained from multicriteria outranking methods such as for instance ELECTRE or PROMETHEE. As a consequence, they are often known to be non-symmetric, making two-dimensional representations seldom possible. An optimization model is defined and a particle swarm optimization algorithm is used to solve it. Validation is based on artificial tests. Finally, an illustrative example is given.
