摘要:  以实际的光通讯生产线在制品数量为研究对象,研究生产线在制品数量的设定方法。分别运用分段计算方法和排队论的[M/M/s]∶[∞/∞/FCFS] 模型以及[M/M/s]∶[N/∞/FCFS]模型研究其目标值,分析结果表明: [M/M/s]∶[N/∞/FCFS]模型建立的目标值切合实际,故以此为目标,提出生产管理改善措施,实现在制品数量目标控制,使在制品数量降低50%,生产周期减少50%,流动资金占用减少1875万元,很好地验证了该方法的合理性和科学性。

Abstract:  To reduce the cost, it is necessary to minimize the work in process (WIP) in a production line. In this paper, a case study is conducted on how to determine the WIP for an optical communication component production line. The problem is modeled by queuing models [M/M/s]∶[∞/∞/FCFS] and [M/M/s]:[N/∞/FCFS]. Based on the models, analysis is carried out to optimize the WIP. Based on the analysis results, redesign is made and implemented to improve the performance of the production line. Consequently, both the WIP and production lead time are reduced by 50%. This is a significant improvement.

Key words: work in process (WIP), cycle time, queuing theory
