摘要: 粗糙集的公理系统是粗糙集理论与应用的基础。覆盖粗糙集是粗糙集理论的自然的有意义的推广。基于Xu等提出的新的覆盖粗糙集模型,研究了新模型的公理系统,用4条简洁且相互独立的公理刻画了覆盖粗糙集。这些研究有助于覆盖粗糙集理论研究的深入和完善。

Abstract: Based on the new model of covering rough sets proposed by xu and zhang,the axiomatic system of covering rough sets on covering approximation space was studied, it consists of 4 axioms which are simple and independent. The research is helpful to covering r
