To solve the problem of efficient logistics support for aviation enterprises, a VED classification method of air materials based on improved group AHP is proposed. Combined with the three-level storage model of the air materials, the corresponding storage strategy is given, and the corresponding spare parts storage model is formulated using the decision tree theory. Based on the basic idea of improving the group hierarchy analysis method, the final weight judgment of the index set is obtained, and the attribution situation of the 3 storage modes of air materials is determined with the final composite weight. The results of example show the method improve the accuracy of VED classification of air materials.
