Abstract
In this paper, we first define the concepts of covering decision systems and their reducts. We then develop a sufficient and necessary condition for attribute reduction and construct the dicernibility matrix of attribute reduction, by which we can compute all the reducts of covering decision systems. Finally, an example is employed to illustrate our idea in this paper.
