A novel hybrid soft set model called intertemporal hesitant fuzzy soft set is proposed, and then, it is showed how it can deal with group decision making problems. This model can be used to incorporate hesitant information that varies across time, when the alternatives are described by their degree of agreement with various characteristics. According to the period of time (whether it is indefinitely long or with a known termination date), the proposed model is, respectively, called long-term and short-term intertemporal hesitant fuzzy soft set. Corresponding group decision making approaches are provided, where the application of Quasi-Hyperbolic discounting permits to deal with the time-inconsistent experts’ preferences. Both the effect of scores of hesitant fuzzy elements and the effect of uncertainty contained in hesitant information are considered in the proposed decision approaches.

跨期犹豫模糊软集：在群体决策中的应用

提出了一种新颖的混合软件集模型，称为时间跨度犹豫模糊软件集，并说明了如何解决群体决策问题。当通过备选方案与各种特征的一致程度来描述备选方案时，可以使用此模型来合并随时间变化的犹豫信息。根据时间段（无限长或终止日期已知），所提出的模型分别称为长期和短期跨期犹豫模糊软集。提供了相应的群体决策方法，其中准双曲折现的应用允许处理时间不一致的专家的偏好。
