摘要：

针对以人为主的U形混流装配线的生产效率展开研究。提出了基于合作的工作站内任务分工策略，考虑工人行走对平衡的影响,利用强制节拍装配线平衡方法确定了工人的基本任务分工;通过合理设置工位间缓存以及改变工作优先序,变强制节拍为自由节拍,只在源端设置一个固定节拍来保持生产压力；通过合作使工人之间的任务负荷更加均衡。仿真研究结果表明:在生产压力较小的情况下，只需变强制节拍为自由节拍，即可有效地提高生产效率；而在生产压力较大的情况下，变强制节拍为自由节拍以及合作均能有效地提高U形混流装配线的生产效率，合作还能提高工人之间的任务均衡率。

关键词: 平衡模型, 自由节拍, 合作, 仿真

Abstract:

The purpose of this paper is to improve the production efficiency of human-oriented U-shaped mixed model assembly lines.The cooperation based task assignment strategy within workstation was proposed;the influences of workers movement on balance were considered.The basic task division was decided by forced rhythm assembly line balancing model.The line was changed to free rhythm line by setting up reasonable buffer and changing the work order;a fixed source send rhythm was set up to maintain the production pressure.The task balance rate was improved by cooperation.Simulation results show the following conclusions:changing forced rhythm to free rhythm is effective enough to improve the production efficiency of U shaped line when there is lower production pressure;changing forced rhythm to free rhythm and cooperation can all improve the production efficiency effectively when there is higher production pressure,cooperation can improve the task balance rate as well.

Key words: balancing model, free rhythm, cooperation, simulation
