摘　　要：大规模定制和多样化需求的制造模式使板式定制家具企业面临严峻的挑战,为了提升板式定制家具企业生产线效率,缩短生产交付周期,以板式定制家具企业某车间生产线为研究对象,通过价值流图研究生产线情况,识别出生产线负荷平衡率低、生产布局不合理及在制品库积压等问题,利用因果分析法分析问题成因。运用流程程序分析法、5W1H提问法和ECRS原则、双手动作分析等工业工程法对瓶颈工序进行改善;对不合理生产布局进行调整,结合改善效果,绘制了未来价值流图;针对生产线负荷不平衡的问题,建立0-1整数规划数学模型,并运用LINGO求解最小生产节拍等。结果表明,优化效果明显,瓶颈工序作业时间减少,生产线负荷平衡率由52.58%提升至86.74%,平滑性指数由10.45降至5.99,板件搬运效率提升,在制品库存得到显著改善。本研究旨在优化板式定制家具企业生产线,提升生产线负荷平衡,实现精益化生产,以期为板式定制家具企业生产线平衡优化提供新思路。The manufacturing mode of mass customization and diversified demand poses severe challenges to panel customized furniture enterprises.In the fierce market competition environment,in order to achieve sustained growth,panel customized furniture enterprises must improve their manufacturing hardware.How to reduce costs and improve efficiency has become a problem that enterprise managers must pay attention to.A smooth production line can not only reduce on-site waste and improve product quality,but also reduce production costs and improve production efficiency.Fully utilizing lean production and various improvement methods to optimize production lines and establish more flexible methods and flexible production have become a very important improvement direction for panel furniture manufacturing enterprises.Value stream mapping(VSM)is an important improvement technology in lean production,which is very effective in identifying production waste issues and improving production efficiency.However,it is rarely applied in panel customized furniture enterprises.Therefore,applying the VSM method to the panel furniture industry is of great significance.In order to improve the efficiency of the production line of panel customization enterprises and shorten the production delivery cycle,this study takes a workshop production line of a panel customized furniture enterprise as the research object.Through the value flow diagram method and on-site production line adjustment,the existing main problems are identified.The cause and effect analysis method is used to analyze the reasons for the imbalance of the production line,and improvement plans are proposed.Process program analysis,5W1H questioning,and ECRS principles are used.Industrial engineering methods such as hands-on motion analysis are utilized to improve bottleneck processes.Adjustments were made to the unreasonable production layout,and a future value stream map was drawn based on the improvement effect.A 0-1 integer programming model was established for the problem of produ
