SYSTEM FOR AIDING MULTICRITERION DECISION WITH AUTOMATIC GENERATION OF EXPLANATIONS, AND CORRESPONDING METHOD

摘要

The system comprises: - a knowledge base (1) forming a multicriterion decisional model, storing, in a hierarchized manner over several levels, criteria relating to a given decision made, possible values associated with the criteria, weights of criteria associated with the criteria, and interaction weights associated with the interactions between criteria, a given combination of possible values of criteria forming an alternative, - an evaluation module (2) for determining a score for a given alternative, as a function of the weights of criteria, of the interaction weights, and of the values, - a module (4) for determining, for criteria belonging to several levels of the model, contributions of the weights of criteria, of the interaction weights and of the values, in a score evaluated by the evaluation module for a given alternative, - a module (3) for generating explanations about the score of a given alternative, on the basis of contributions determined by the determination module.
