Research on simulation and optimization of sheet metal mixed-flow production line
Based on the sheet metal mixed-flow production line of an elevator sheet metal processing company,the production sequence and bottleneck problems in the sheet metal production link are op-timized by virtual simulation method.According to the actual production status of an elevator door panel production line,the simulation model of the production line is established,and the production sequence of the sheet metal mixed-flow production line is optimized based on the workpiece completion time,equipment idle time and total equipment switching time,combined with genetic algorithm.At the same time,by analyzing the influence of added location and capacity of the buffer on the output of sheet metal production line,the problems of production line blockage and unbalanced utilization rate are solved.The results show that the optimization of the production line is effective,the overall time of the optimized production sequence is shortened by about 15％compared with that of the original production sequence,and the average utilization rate of each workstation equipment is increased by 9.6％and the output is increased by 14.15％through the appropriate buffer setting.
