摘　　要：白车身焊装线作为汽车生产制造中的一个关键工艺过程,其产出率决定着汽车的产量。通过改善机器的故障率提高生产节拍,添加缓存区来改善焊装线的不平衡状态等方法都可以用来增加产量。然而不能改善所有机器的故障率,而且过多的添加缓存区反而会占用厂区空间成本。因此,通过仿真研究找出瓶颈工位,然后改善该工位机器的故障率来提高产量。通过试验设计的方法,确定最合适的缓存添加位置和缓存容量设置来提高产量。最后分析缓存区与故障率两因素对产量的共同作用,确定最终方案,将改善后的焊装线与改善前的进行对比,证明改善措施的有效性。The welding line of BIW is an improtant technology in automobile manufacture,so it＇s output rate decide auto production. For increase productin,it could by the way of improveing the failure rate of machine to improve the cycle time,or add buffer to improve welding line unbalance and so on. But it is impossible to improve the failure rate of all machine,and the number of buffer should appropriate,otherwise it will occupy the cost of factory space. Therefore,this paper finding the bottleneck station by simulation,then improve the rate of bottleneck station to increase production. Then,it could comfrim the approriate loaction and capacity of buffer to increase production. Finally,this paper analysis the interaction between buffer and failure rate,then observe the result before and after improvement,and then prove the feasibility of this method.
