摘　　要：针对机械式穴播器装配线上在制品(Work In Process,WIP)主要依靠管理人员经验进行定性控制的问题,采用多点控制的方法对装配线上在制品进行定量优化。首先运用约束理论(Theory Of Constraint,TOC)结合推、拉两种生产方式对装配线进行分段研究,在分段节点设立瓶颈缓冲区、并联缓冲区和风险缓冲区;然后根据工位故障持续时间与物料消耗速度计算出缓冲区最优容量,得出机械式穴播器装配线在制品多点控制优化方案。通过对某企业机械式穴播器装配系统进行Flex Sim仿真,验证了方案的可行性。A multi-node control scheme was proposed to optimize the Work In Process （WIP）on mechanical dibbler assembly line. Theory Of Constraint（TOC） was combined with the production modes of push and pull to divide assembly line into segments first. Next, bottleneck buffer,parallel buffer and risk buffer were seted up in the subsection node. Then calculated the optimal ca- pacity of the buffer according to the duration of the station failure and the material consumption rate, obtained the optimization scheme of multi-node control of WIP in mechanical dibbler assembly line. Finally, FlexSim was used to simulate the mechanical dibbler assembly system of an enterprise, verified the feasibility of the scheme.
