基于集值信息系统上的拟序关系讨论了集值决策表的合成,对合成集值决策表的相关属性特征进行了研究,进一步给出了对象合成集值决策表和属性合成集值决策表及其属性特征。
In this paper,composition of the set-valued decision tables are discussed based on the preorder relation on set-valued information systems.The characterizations of composed set-valued decision tables are investigated.Furthermore,the characterizations of object-composed and attribute-composed set-valued decision tables are also discussed.
