摘要
本文研究粗糙集的粗糙度问题。首先仔细分析了Pawlak粗糙集的粗糙度!得到了粗糙集粗糙度包容相斥原理;然后将结果推广到模糊集理论领域,对研究模糊关系下模糊粗糙集理论有一定的作用。
In this paper, the orughness measures of rough sets is studied. Firstly, the roughness mesures of Pawlak rough sets is analysized in detail,and a inclusion-exclusion principle on rough sets is obtained. We also extend these results to fuzzy rough sets,which is some significance for deeply study of fuzzy rough sets theory.
