Resumen de Characterization of the linear rational preference structures

Sixto Ríos Insua , Jacinto González Pachón

• We consider the multiobjective decision making problem. The decision maker's (DM) impossibility to take consciously a preference or indifference attitude with regard to a pair of alternatives leads us to what we have called doubt attitude. So, the doubt may be revealed in a conscient way by the DM. However, it may appear in an inconscient way, revealing judgements about her/his attitudes which do not follow a certain logical reasoning.

  In this paper, doubt will be considered as a part of the information revealed by the DM. In the next paragraphs we will see what we mean with the term logical reasoning introducing the rational preference structure concept.
