摘　　要：首先分别分析了结构树和粗糙集在故障诊断中的应用情况 ,然后考虑将它们结合起来 ,用结构树构造粗糙集的决策表 ,用粗糙集简化结构树生成的规则集 。The applications of structure tree and rough set to fault diagnosis are discussed respectively.The decision table of rough set is built with structure tree and the rule set generated from structure tree is simplified by rough set.And the design of an expert system for vehicle fault diagnosis based on the combination of structure tree and rough set is presented.
