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
