Dimension theory framework, despite its computational complexity, is considered here, pursuing in principle a decomposition of arbitrary preference relations in terms of linear orderings of alternatives. But we shall then stress that consistency should not be necessarily associated to a linear ordering. In this way, alternative decompositions of a preference relation can be proposed to decision maker, allowing an effective search for a useful representations of alternatives in terms of possible criteria. Such decompositions of our preference relations will then become the basis of a future decision aid model, always with the restricted aim of allowing the decision maker a better understanding of the problem. Inconsistencies may be not simply suppressed but understood, since they may contain relevant information.engbook parthttps://ieeexplore.ieee.org/document/4295546/http://ieeexplore.ieee.orgrestricted access510.64Fuzzy rationality measuresDimensionLógica simbólica y matemática (Matemáticas)1102.14 Lógica Simbólica
