| 摘 要： | 针对交可约粒度空间中覆盖、基和粒结构的关系,结合偏序关系的哈斯图,给出一种约简粒度空间的方法.另外,通过限定上、下近似算子的取值范围,重新定义了交可约粒度空间上的粗糙集模型,并讨论了其相关性质.

| Abstract: | In terms of the relationship among the covering,the basis,and the corresponding granular structure,a new method is given for reduce the granular spaces,by using the hasse diagram based on partial order relation.In addition,by limiting the domain of rough approximation operators,a rough set model is redefined,and the natural of rough set model is examined also on the union reducible granular spaces. |
