Layout optimization analysis of connecting rod forging production line based on resource balance analysis

Aiming at the problems of insufficient utilization of production line resources and high equipment waiting time in the process of connecting rod forging, two optimal layout schemes for series and parallel production lines are designed. The calculation shows that the workshop utilization rate of the parallel scheme is 74%, which is slightly better than that of the tandem production line, whose workshop utilization rate is 73%, and it is adopted as the optimized plan. Through the production line resource balance analysis method, the optimized plan is compared with the production line unbalanced loss rate of the original layout and the production line smoothness index. The balance loss rate was reduced from the original 31% to 13%; and the production line smoothness index was reduced from the original 7.19 to 2.37, those show that the optimization scheme was effective.
