Aircraft Spare Parts Supply Chain Based On 3D Printing

Compared with other industries,the supply chain of aviation industry is the most complex and longest.Since the demand for aviation spare parts is random in nature,it can cause problems such as difficulty in forecasting the inventory of aviation materials and high cost of aviation materials inventory.The airline’s aerial material stock can take up a large amount of capital,yet most of them are never issued.Therefore,the act of over-stocking the aviation materials to secure the supply of aviation materials hinders the airline’s business development.The unscientific and unreasonable management of airline materials has led to high costs for airlines.Therefore,the improvement of airline material security and airline material management is closely related to the economic efficiency of airlines.This thesis firstly analyzes the causal relationship between the traditional aviation spare parts supply chain and the aviation spare parts supply chain with the introduction of 3D printing technology,based on which the system dynamics models of the traditional supply chain and 3D printing supply chain are constructed.The numerical changes of total inventory level and spare parts shortage as well as the impact of the changes of spare parts demand on the system are analyzed by comparing the two supply chains through simulation.After that,this paper constructs the system dynamics models of traditional supply chain,decentralized3 D printing supply chain and centralized 3D printing supply chain considering lateral scheduling,and analyzes the impact on the system by simulating and comparing the numerical changes of base inventory level and lateral scheduling volume as well as the changes of spare parts demand of the three supply chains.Finally,a cost equation is constructed to compare the costs of the three spare parts supply chains.By comparing the system dynamics model simulation and cost calculation,the following conclusions are drawn.The introduction of 3D printing technology into the aviation spare part.
