UN NUEVO MODELO PARA AGREGACIÓN DE PREFERENCIAS MULTICRITERIO BASADO EN LÓGICA DIFUSA

Resumen

There are cases in which the model used by the multicriteria decision making method ELECTRE III calculates values of outranking credibility which do not adhere to the common sense of a real decision maker. This work proposes a new model for the construction of fuzzy outranking relations. The model is derived as a compound predicate that integrates statements expressed in natural language and with the use of fuzzy logic calculates the degree of truth of the outranking relation aSb, to provide results more consistent with human reasoning.
