摘要
模糊粗集理论是粗集理论的重要推广,研究广义近似空间下模糊粗集的模糊性具有重要的意义。文章研究了由对象-属性值偶对构成的广义模糊近似空间下模糊集合的粗模糊度问题,给出了其模糊度表示,并讨论它的性质。
The fuzzy rough sets theory has been regarded as a generalization of the rough sets theory initiated by Pawlak,it is very usefull to research the measure of fuzziness of a fuzzy rough set under Generalized Approximation Space.In this paper,we have reserached the rough-fuzzniess of fuzzy rough sets under the generalized approximation space comprised by fuzzy objects attribute-values pairs.A measure of rough-fuzziness of fuzzy sets is introduced,and its properties are studied.
