With the global emphasis on the development of the manufacturing industry, countries began to vigorously develop and reclaim manufacturing industry. As a global manufacturing power, China's manufacturing industry occupies a pivotal position in the national economy. In this paper, we take a brand stopwatch production line of S company as the research object, we find that there are many problems in the production line in S company, such as work-in-process backlogs, unbalanced process schedules, and confusing equipment management. Therefore, we analyse the current situation of the production line, we measure the standard time of its process operation, we research the bottleneck process, and we use the Flexsim simulation software to model and simulate the production line. we deeply analyze the blockage link and low utilization rate of each process, we improve the bottleneck link, and we merge, decompose or reorganize the workstations. Finally, the balance of the production line of the optimized factory has been significantly improved, the number of processes in the four production lines has been simplified, and the production balance rate reaches more than 60%, especially motherboard pre-processing line, assembly test line, and packaging line reach more than 80%, which greatly reduce the backlog of work-in-process and the waste of resources. then we optimize its product line based on ECRS rule, and we implement 5S management to promote the efficiency of its production line.
