【摘要】：为了更充分的利用数据信息,本文提出了以犹豫模糊集作为概念的反馈外延。进而给出了考虑犹豫度的犹豫模糊集间的关系与运算;基于此运算,定义了模糊概念的外延包络,并利用包络来集结多因素的偏好信息,为了给出不完整信息下的犹豫模糊群决策方法,本文还提出了一种缺失信息的填补方法,最后给出群决策步骤,并通过实例对上述理论方法进行了应用。
[Abstract]:In order to make full use of data information, this paper presents a feedback extension based on the concept of hesitant fuzzy sets. Furthermore, the relation and operation among the hesitant fuzzy sets considering the degree of hesitancy are given. Based on this operation, the extension envelope of the fuzzy concept is defined, and the preference information of multiple factors is gathered by using the envelope. In order to give the method of uncertain fuzzy group decision making under incomplete information, this paper also proposes a method to fill the missing information. Finally, the steps of group decision making are given, and the above theory and method are applied through an example.
