Resumen

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.
