摘要 提出了格值决策表中分配协调集的概念并讨论了它的基本性质,给出了分配协调集的充分必要条件,借助区分矩阵与区分函数给出了计算分配约简的方法. The concept of distribute consistent set for lattice-valued decision table is proposed and some sufficient and necessary conditions for an attribute set to be distribute consistent' set are given. The discernibility function of distribute reduc- tion is constructed and from which an approach for distribute reduction is provided.
