双极值模糊软集

摘要

In this paper, the notion of bipolar-value fuzzy soft sets is proposed. The complement, union, intersection, "and", "or" operations are defined on the bipolar-value fuzzy soft sets. The basic properties of bipolar-value fuzzy soft sets are also presented and discussed.%提出了双极值模糊软集的概念,给出双极值模糊软集的补、并、交、“且”及“或”运算,并讨论了它们的性质.
