Abstract: Rough set is a new way to deal with data, while statistics is a traditional one. Both of them have merits and shortcomings. In this paper, the authors bring forward a new way to combine these methods. And apply this new way to a decision support system to test the accurateness of this new way. In order to simple this procedure, the authors use a new and simple way to deal with the data sets, which is between the traditional way of reduction and the way of Skowron's Matrix. After being tested by a set of data, it is proved to be right and effective.

摘要： 粗糙集理论是近代新兴的数据处理方法，概率统计方法是传统数据处理方法，两者各有其优缺点。文章在对粗糙集理论进行深入研究的基础上，提出将两种方法结合，并在决策支持系统中应用，在系统的实现过程中提出了新的处理方法。
