Furthermore, we use the standardized method to transform upper and lower approximations with no inclusion relation into upper and lower approximations with an inclusion relation. It is verified by an example that this method can effectively solve the problem that the upper and lower approximations of the multigranularity fuzzy rough set in two universes have inclusion relation %K 模糊集 %K 粗糙集 %K 双论域 %K 多粒度 %K 上近似 %K 下近似 %K 标准化 %K 包含关系 %K 充分条件< %K /br> %K fuzzy set %K rough set %K dual domain %K multi-granularity %K upper approximation %K lower approximation %K standardized method %K inclusion relation %K sufficient condition %U http://tis.hrbeu.edu.cn/oa/darticle.aspx?type=view&id=201804046
