Research on Aviation Material Inventory Management Strategy Based on System Dynamics

Based on summarization of existing literatures on the aviation repairable spares parts inventory system,the factors that affect repairable spares' parts inventory system are analyzed.A cause-and-effect diagram and a system dynamics flow chart about inventory system are drawn.The system dynamics model is built based on the flow chart.The model is also realized by software Vensim.The result shows that maintenance level and inventory adjustment time are key factors that affect inventory system.Delivery delay has less effect on the inventory system.Some corresponding solutions to optimize aviation repairable spares parts supply inventory are put forward.
