Support System for Spare Parts—A Dynamics Model
The logistics of spare parts shows the characteristics of dynamics. We establish a support system based on demand-pull model. This paper analyses the feedback control mechanism of the system and the mathematical principles of the dynamics of the supply-demand model of spare parts based on system dynamics. Then we build a system state model, analyzing the dynamic actions of the support system. Our study shows that: ① Excessive logistics delay may affect the stability of the system; ②The stability and performance of the support system of spare parts based on the demand-pull model are closely related to the supply chain management system and technical conditions, also depend on the interactions of multiple factors. Then we get the value threshold of the key parameters to make the system stable, and test the impacts of logistics delay on the stability of the system. Finally, through system dynamics simulation, we optimize the system.
