Managing product lines that share a common capacity base
通过一家制造企业的案例研究，用系统动力学模型分析共享产能的产品线中，成品需求波动如何导致服务零件供应波动和交货延迟，并提出将两条产品线生产解耦以改善服务零件业务绩效。
Abstract This paper examines the difficulties of maintaining competitive delivery times on product lines that share a common capacity base. The analysis is derived from a case study of a manufacturing firm producing finished product and service parts at a single plant. A system dynamics simulation model is used to represent production and ordering policies of the firm and its distribution network. Simulation analysis shows that these policies cause demand volatility for the finished product to be converted into supply volatility of service parts, leading to long parts delivery times and loss of service parts market share. To improve the performance of the service parts business, the production of finished product and parts should be decoupled, so the supply of the two product lines becomes independent. The results are discussed for the general multiproduct‐line case. A brief report of implementation results is included.
