This paper expounds the concepts and makeup of equipment maintenance data, applies the the- ory of rough set into the processing of equipment maintenance information, and defines a new attribute importance degree, which is used as heuristic information, combining with mutual information and infor- mation entropy. Then, it puts forward an improved method of attribute reduction based on attribute impor- tance degree and mutual information, and the arithmetic is validated through reduction of equipment ma- intenance data. The experiment results prove that the arithmetic is more accurate and the results obtained accord much more with actual situations, which can provide decision-making basis for equipment mainte- nance support.
