摘要: In the process of group decision making (GDM), preference relations (e.g. fuzzy relation and multiplicative relation) are very popular tools to express makers' preferences, especially when a set alternatives (or criteria) compared. However, most existing don't consider hesitancy information, which allows makers provide all possible values comparing two criteria), is common situation in daily life. this paper, we first define concept hesitant study its properties, based on give an approach GDM. Motivated by set, introduce develop series aggregation operators. Hesitant also defined useful tool their preferences over alternatives, then applied Additionally, example given illustrate our results.
