In the packaging enterprise inventory management, the difference of the packing material price is not very huge, thus the ABC classification cannot classify the material well. The Analytic Hierarchy Process classification is not objective, and matrix consistency check is too complicated. In order to solve this problem, the fuzzy analytical hierarchy process was adopted to classify raw materials. Compared with the results of current method, it could classify the packaging material inventory more objectively. FAHP is more scientific and effective than the ABC classification and the Analytic Hierarchy Process.
