Supply-demand Joint Inventory - A System Dynamics Model

摘要

Based on the general process of supply chain management, this paper discusses the differences between joint inventory supply chain management and the general inventory supply chain management. Through establishing a system dynamics model, we make quantitative analysis of the key parameters of the supply chain, studying the impact of bottlenecks and the bullwhip effect on the whole supply chain, and provide reasonable theoretical support for enterprises to develop, improve supply chain management. The study shows that:1) the increase of T1 (the order time of raw material) not only can improve the stability of the system, but also can reduce the average inventory, 2) in the case of other parameters being fixed, there exists a critical value B. When T1
