摘要：
In covering generalized rough set theory it is necessary to discuss the relative relation between knowledge represented by covering. This paper proposes two kinds of relative reductions in a family of coverings, and constructs two discernibility matrixes to investigate the structure of all relative reductions. Also, the reduction of ordered information system under dominance relation is used to show an application of the method of reduction introduced in this paper.
