摘要
提出了区间值模糊粗糙集的上下近似,并且利用区间值模糊集的截集定义了区间值模糊粗糙度量.在此基础上讨论区间值模糊粗糙集和区间值模糊粗糙度量的性质.
Both rough sets theory and interval-valued fuzzy sets theories are emerging as powerful tool for managing uncertainty, incomplete and imprecise information. An integration between interval- valued fuzzy sets theory and rough sets theory is developed in this paper. Furthermore,a parameterize roughness measure of an interval-valued fuzzy set is given followed by an analysis of its properties.
