泛系动态粒度广义近似粗糙集

Generalized Approximation Rough Set of Pansystems Dynamic Granularity

由于不同粒度形成的等价类之间的联系与转换构成系统中的泛对称,因此用关系粒度的多动与少动来拟化等价类的多变与少变,针对任意二元关系的粗集广义近似,结合动态粒度思想,在任意二元关系下,提出泛系动态粒度广义近似粗糙集,它提供了一种新思路来处理广义粗集近似关系,使粗糙集理论的应用更实用。

With the contact of equivalence relation of different granularities and the pan-symmetry in the transform system, so it can simulate the changeable and unchangeable equivalence classes to use the hyperactivity and sedentary relationship granularity.For the rough set of the generalized approximation in any binary relation, combined with the thought of the dynamic granularity,the paper proposed the generalized approximation rough sets of pansystems dynamic granularity in any binary relation, which provides a new thought to process the relation of the approximation of the generalized rough set, as well as makes the rough set theory more practical in applications.
