The Inventory Management Of SC Corcopration's Aviation Spare Parts

The civil aviation shipping industry has the remarkable scale economy to become the mutual recognition, except for displaying in the financial economy, management of the economical route network and the marketing network, the navigation material scale efficiency is also cannot be neglected.There are two typical characters in the aviation shipping industry, one is the huge fixed capital investment, and the other one is the long investment repayment cycle. The reserve of aviation spare parts is an urgent question which needs to be solved. As a kind of special products, the aviation spare part is unable to carry on its demand forecast by using general theories, so the phenomenon of the high spare part storage in airline companies is generally existed. On the one hand, the unnecessary reserve takes the massive funds, reduces the fund handling speed, and seriously affects the efficiency economic of the airline company; On the other hand, certain stock insufficiencies have caused the low guarantee rate level directly.The supply chain theory, used in the logistics management, is used to control the material inventory in this article. In the second chapter, the characters of the supply chain purchase management in aviation spare parts are discussed through the related knowledge of the supply chain, then the function, restriction factors and existed problems of the aviation spare parts stock control system are made clear. Through the main introduction of the consumption characteristic, the correlated aviation material stock control parameters, the consumption forecast method and the economical ordering model EOQ. how to determine the quantity of the purchase order again, actual quantity of purchase order and an ordering model keeps in stock under any condition are elaborated in the aviation material consumption ordering model in the third chapter. The correlated parameters of the rotatable are determined through the research of the circulation stock method in the fourth chapter and also the security policy of it. It is the smallest useable stock that equals to the addition of the opens trades numbers in transportation time in the apron and the security quantity during this period. If the useable stock is lower than the smallest stock, then the corresponding safeguard measure must be taken. In order to achieve the goal of solving questions, I confirm the feasibility ofthis model through concrete enterprise's production data as a practitioner of the aviation shipping enterprise.
