The relation between rough set algebra and lattice implication algebra was studied, and the method of constructing lattice implication algebra from rough set algebra was presented.
讨论粗糙集代数与格蕴涵代数的关系以及由粗糙集代数构造格蕴涵代数的方法。
With the definition about reasonable complement operation of the fuzzy rough set,a expanded rough set algebra is constructed by using the method of formula.
定义了模糊粗糙集合理的补运算,从而利用公理化方法构造出推广了的粗糙集代数。
Based on this,the fuzzy rough set algebra is defined,and some simple properties of the fuzzy rough set algebra are discussed.
在此基础上定义了模糊粗糙集代数,并讨论了模糊粗糙集代数的简单性质。
