By means of the methodology of rough set,different attribute classification methods for decision systems are first analyzed in this paper,and the attribute significance as well as the extremely small subset of the attribute relative reduction caused by a classification variety is discussed.
应用粗糙集的方法,分析决策系统中不同的属性分类方法,以及不同分类方法引起的属性重要性与属性相对约简极小子集的变化情况,寻求属性分类方法与属性约简结果相互影响的内在因素,给出高效的属性分类方法和合理确定约简子集的策略,生成策略对应软件的实现算法,并运用软件实现算法来选取相对约简子集。
The authors introduce two new concepts of L - nested sets which are based on the concepts of minimal set and maximal set where L is a completely distributive lattice.
