摘要
粗糙集理论作为一种新兴的处理不确定性问题的有效工具正越来越受到人们的关注。在介绍粗糙集理论基本内容的基础上,对粗糙集理论与模糊集理论、随机理论、灰色理论等其它用于处理不确定性问题的理论工具从差异性上进行了分析;同时讨论了它们之间的互补性问题,并构建了相应的互补模型;最后指出了粗糙集理论对于进一步丰富和完善处理不确定性问题的理论体系的重要性。
As an uncertainty theory,the rough set theory is engaging more and more people＇s Attention. The basic concepts of rough sets are introduced. Based on the introduction,the difference between the rough set theory and the other uncertain theories, such as fuzzy set theory, random theory and grey theory are analyzed. At the same time, the complementary problems are investigated, and furthermore the complementary models are established.At last, the importance of the rough set theory on making the indefinite theory more perfect is pointed out.
