Abstract

En el contexto de toma de decisiones multicriterio y bajo ciertas circunstancias, puede ocurrir que no se pueda expresar una cierta valoración mediante una única etiqueta lingüística, ya que puede haber duda en esa valoración. En este trabajo, presentamos un modelo de consenso para problemas de toma de decisiones en grupo con relaciones de preferencia intervalares lingüísticas. Este modelo está basado en dos criterios de consenso, una medida de consenso y una de proximidad, y en el concepto de coincidencia entre preferencias. Calcularemos ambos criterios en los tres niveles de representación de una relación de preferencia y diseñaremos un mecanismo de realimentación automático para guiar a los expertos en el proceso para alcanzar el consenso. || In some circumstances a decision maker, expert, in a group decision making problem cannot express his/her preferences with a unique linguistic fuzzy preference because he/she is dubious into some preferences. In this paper, we present a consensus model for group decision making problems with interval fuzzy preference relations. This model is based on two consensus criteria, a consensus measure and a proximity measure, and on the concept of co- incidence among preferences. We compute both consensus criteria in the three representation levels of a preference relation and design an automatic feedback mechanism to guide experts in the consensus reaching process.
