Calculs à l'aide de mots : vers un emploi de termes linguistiques de bout en bout dans la chaîne du raisonnement

In recent works, we have proposed a graphical model to represent linguistic preferences called LCP-nets. LCP-nets have been implemented and used in a specific use case of industrial engineering. In this paper, we consolidate this contribution in formalizing it through a set of notations and computation rules in order to guarantee its durability and its reusability to other multi-criteria decision contexts. A search algorithm is given and a discussion is proposed about the classical properties that such graphical models must have: dominance testing and optimization queries.
