摘要 在覆盖粗糙集的并可约粒度空间模型研究中,针对从覆盖到基的约简规则,结合偏序关系的哈斯图,给出一种对覆盖约简的新方法.另外,在并可约粒度空间上讨论了粗糙集模型的相关性质. Based on the research of the union reducible granular spaces on covering rough set, aiming at the construction rule from the covering to the basis and combining with the Hasse diagram of partial order relation, a new reduction method is proposed. Meanwhile, the relevant properties of rough set model based on the union reducible granular spaces are studied.
