In order to solve the problem that the acquisition supply work of aircraft equipment maintenance spare parts lacks the scientific standard basis in our army, this paper studies the acquisition supply standards. From the 4 aspects of annual support plan formulation of aviation equipment maintenance spare parts, spare parts purchase outlay prediction, stock reserve control, and support effectiveness evaluation, this paper analyses the problems in the support theory research and practice of our military aviation equipment maintenance spare parts, combined with the actual support in our army and using the multidisciplinary method, proposes the solution idea and methods in aspects of the screening methods of spare parts in the standards, the influence factors of standard formulation, the life and demand distribution of spare parts and the measuring method of the quantity of spare part in the standards. The results show that this idea has important reference value to the research and formulation of the acquisition supply standards system of aviation equipment maintenance spare parts in our army.
