Improving Overseas Aftermarket Aircraft Spare Parts Supply Logistics Using Simulation Modeling

Computer simulation technology not only enhances the understanding of complex systems but also provides crucial support for decision-making and design, offering an effective method for studying the supply of aftermarket aircraft spare parts (ASPs). The demand for ASPs is different from that for aftermarket general-equipment spare parts in terms of supplier quantity, supply process, and supply conditions. These differences in demand characteristics lead to changes in supply logistics. This study investigates the factors affecting the aftermarket ASP supply and proposes an overseas supply logistics model for aftermarket ASPs. A simulation model was used to reproduce the aftermarket ASP supply and compare different scenarios. The ordinary mode and full-lift-cycle coverage mode are modeled to compare their efficiency. The full-lift-cycle coverage mode was also tested to evaluate the feasibility of its supply process. The results confirm that the full-lift-cycle coverage mode improves supply logistics performance, offering benefits for the overseas supply of aftermarket ASPs for Chinese-made civil aircraft.
