Abstract: In this paper, we present a priority degree method of hesitant fuzzy linguistic term sets (HFLTSs) based on a type of G function. First, we obtain several invalid examples by using Rodríguez et al. and Lee et al.’s method of HFLTSs. Considering these problems, second, after transforming HFLTS into the interval number and proposing a priority degree method of the interval number using the G function, we present a priority degree method of HFLTEs. Finally, we compare both Rodríguez et al.’s decision-making method and lee et al.’s decision-making method with our priority degree method. The result shows that our priority degree method is more rational.
