Complex product manufacturing faces a great challenge in coordinating the supply of components. Manufacturers of complex products are highly sensitive to supply chain delays as insufficient delivery of any components would suspend the entire assembly line. This article focuses on the capacity planning decisions of the supplier and manufacturer for coordinating the component supply of complex product manufacturing. A system dynamics model is developed to capture the dynamic interaction of supplier's production capacity planning and manufacturer's component inventory expansion capacity planning. Based on simulation results and analysis, the following guidelines are proposed for making capacity planning policies: 1) Information sharing should be advanced to help the manufacturer and supplier make capacity planning policies; 2) With only limited information about supplier's production capacity, it may not be favorable for the manufacturer to coordinate component supply by acquiring replenishment from backup suppliers; and 3) With only limited information about manufacturer's component inventory expansion capacity, it is better for the supplier to keep a higher production capacity.

复杂产品制造中零部件供应能力规划的系统动力学模型


复杂的产品制造在协调零部件供应方面面临着巨大的挑战。复杂产品的制造商对供应链延误高度敏感，因为任何组件交付不足都会导致整个装配线暂停。本文重点讨论供应商和制造商协调复杂产品制造的零部件供应的产能规划决策。开发了系统动力学模型来捕获供应商的生产能力计划和制造商的零部件库存扩展能力计划的动态交互。根据仿真结果和分析，对产能规划政策的制定提出以下指导原则： 1）推进信息共享，帮助制造商和供应商制定产能规划政策； 2）供应商产能信息有限，可能不利于制造商通过向备用供应商补货来协调零部件供应； 3）由于制造商的零部件库存扩张能力信息有限，供应商最好保持较高的产能。
