Study on Electronic Product Assembly Line Balance Based on Integer Programming and Simulation

针对电子产品装配生产线效率低、堆积严重、负荷不均衡等问题,以某公司无线路由器装配生产线为例展开研究。首先,搜集生产数据,分析该生产线存在的问题;其次,基于0-1整数规划构建以最小节拍时间为目标函数的生产线平衡优化模型,该模型考虑了工序与设备、工序与工序间的关联性,以满足特殊工站的需求,并借助Lingo软件编程求解,探究通过合理分配作业工序,降低生产节拍时间,提升生产线平衡率;最后,通过AnyLogic仿真软件建立仿真模型,验证改善后方案的可靠性。验证结果表明,该方案使生产线平衡率由61.8%提高到84%,均衡系数从10.8降到3.5,单位产能由136件/h提高到185件/h,大幅提高生产效率和降低员工负荷,降低了企业生产成本和提高市场竞争力,为电子制造业提高生产线平衡率提供有效的途径。

Aiming at the problems such as low efficiency,serious accumulation and unbalanced load in the assembly line of electronic products,a company's wireless router assembly production line is used as an example for research.Firstly,production data is collected and the problems existing in the production line are analyzed.Secondly,based on 0-1 integer programming,a production line balance optimization model with minimizing beat time as the objective function is constructed,which considers the correlation between processes and equipment,as well as between processes and processes,to meet the needs of special workstations.With the help of Lingo software programming,it is explored how to reduce production cycle time and improve production line balance rate by reasonably allocating work processes.Finally,AnyLogic simulation software is used to establish a simulation model to verify the reliability of the improved scheme.The verification results show that the scheme can increase the balance rate of the production line from 61.8%to 84%,the smooth coefficient from 10.8 to 3.5,the production capacity from 136 pcs/h to 185 pcs/h,greatly improve the productionefficiency and ease the staff load,reduce the production cost of the manufacturingenterprise and improve the market competitiveness.It provides a new way to improve the balance rate of production line in electronic manufacturing industry.
