摘　　要：经典粗糙集理论把元素与分类的关联看成不变的,不便于论域上动态数据的研究,而动态粒度可以从不同角度或层次来分析数据,从而弥补经典粗糙集过于简一的计算机制.在经典粗糙集的基础上结合动态粒度的特点,给出了粗糙集、粒计算、动态粒度和影响度的概念,提出了一种粗糙集的动态粒度算法,并给出其应用.Considere the classification of the association and elements as a constant in the clsssical Rough Set theory,which do not facilitate the research of dynamic data on the universe.While the Dynamic granulation can analyze the data from different angle or levelsa,nd compensate classical Rough Set too singleness computing system consequently.In this paper,based on the clsssical Rough Set with the characteristics of Dynamic granulationt,he author first give the concept of Rough Set,Granular computing,Dynamic granulation and the effect degreea,nd then put forward a new algorithm of Rough Set Dynamic granulation,and gives its application.
