双极值模糊软集运算的研究及应用

Research on Operation of Bipolar Fuzzy Soft Set and Its Application

从参数集的信息角度将双极值软集与模糊集相结合,首先提出了双极值模糊软集的概念,然后定义了双极值模糊软集的交、并、补、且、或运算,并证明了其运算性质。最后基于双极值模糊软集给出一种决策算法,用来解决投资过程中基金选择的问题。

From the view of parameter set information, this paper introduces the concept of bipolar fuzzy soft set by integrating the bipolar soft set and fuzzy set firstly. Then the union intersection complement ‘and＇ ‘or＇ operations are defined, and its operation properties are proved. Finally, based on the bipolar fuzzy soft set, a decision algorithm is proposed to solve the problem of fund selection in the process of investment.
