Abstract: Based on the attributes hierarchy decision table,the attributes hierarchy trees were introduced and the concept of attributes hierarchy decision table was defined.An algorithm was proposed for the rules mining in the attributes hierarchy decision table and numerical examples were employed to substantiate this algorithm.And the experiment indicates that the number of objects in attributes hierarchy decision table is less than original decision table,and the time of implementing attributes reduction is less than that.

Key words: Attributes hierarchy tree,Attribute hierarchy decision table,Rough sets,Attributes reduction
