摘要
介绍了模糊集和粗糙集各自的理论和特点,并讨论了模糊集和粗糙集的各自优点和缺点,有机将两种理论结合起来分析了模糊粗糙集、粗糙模糊集及粗糙隶属函数的性质及应用,引入变精度思想,在粗糙模糊集上定义其上下近似。
the theory and characteristic of fuzzy set and rough set have been respectively introduced and compared,and merit and the shortcoming of the two theories are discussed.By combining the two theories,the nature and the application of the fuzzy rough set,the rough fuzzy set and the rough membership function are analyzed,the upper and lower approximation of the rough fuzzy set is defined by introducing variable Precision.
