Using system dynamics and VENSIM software,this paper establishes the supply chain model of automotive parts,and analy-ses the impact of bullwhip effect on supply chain inventory.By drawing the causality diagram,the three-level parts supply chain model is established,and the time delay,expected inventory duration,inventory adjustment time and moving average time nodes are ana-lyzed.The research finds that these four auxiliary variables will aggravate the"bullwhip effect".According to the characteristics of au-tomobile parts supply chain,the paper puts forward specific strategies to weaken the"bullwhip effect",optimize enterprise inventory management,improve inventory utilization rate,minimize inventory expenditure and improve enterprise cash flow.
