dc.description.abstract [spa] El modelo lingüístico computacional basado en números borrosos discretos ha ganado gran interés entre los investigadores por sus interesantes propiedades. Sin embargo, la investigación realizada hasta ahora en el tema de consenso en grupo con este modelo lingüístico no es suficiente y necesita un mayor desarrollo. Por esta razón, en este proyecto, se propone un modelo de consenso basado en este marco que soluciona algunas de las principales desventajas de las anteriores propuestas en la literatura. Para ello, se presenta una nueva función de agregación en el conjunto de números borrosos discretos y se propone un algoritmo semiautomático que permite a los expertos interactuar y modificar sus opiniones durante el proceso de consenso. Este nuevo modelo logra una tasa de convergencia significativamente mayor en los problemas de toma de decisiones grupales en comparación con los algoritmos existentes. ca
dc.description.abstract [eng] The linguistic computational model based on discrete fuzzy numbers has gained significant interest among scholars due to its attractive properties. However, the investigations on group consensus with this linguistic model are not enough and need further exploration. For this reason, in this research study, we propose a novel consensus model based on this framework that overcomes some of the main disadvantages of the previously proposed methods in the literature. Moreover, we provide a new aggregation function on the set of discrete fuzzy numbers. We propose a semi-automatic algorithm that allows the experts to interact and modify their opinions during the consensus process. This novel method achieves a significantly greater convergence rate in Group Decision Making problems than the existing algorithms. ca
