Abstract
In order to solve the problems of long working hours, complex workflow, and long turnaround time, we applied the lean production concept to the assembly line of our main product, A9815086 automotive wiring harness. The IE method was used to analyze and optimize the production process of the automotive wiring harness assembly(Yi 2006), and the workstations were re-combined according to the ECRS concept to eliminate unnecessary waiting time; the equipment was adjusted nearby to reduce the handling distance so that the number of unbalanced stacking work stations for semi-finished product production was reduced by 50%, the frequency of process turnaround handling was reduced by 42%, and the handling distance was reduced by 32%; the operating time of each production process was measured, and the original process content was adjusted according to the principle of production line balance(Guo 2020). The operating time of each production process was measured, and the original process content was adjusted according to the principle of production line balance, and the production line balance rate was increased from 69.29% to 91.47%, which significantly improved the economic efficiency of the enterprise.
