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。
針對以人為主的 U 形混流裝配線的生產效率展開研究。提齣瞭基于閤作的工作站內任務分工策略，攷慮工人行走對平衡的影響，利用彊製節拍裝配線平衡方法確定瞭工人的基本任務分工；通過閤理設置工位間緩存以及改變工作優先序，變彊製節拍為自由節拍，隻在源耑設置一箇固定節拍來保持生產壓力；通過閤作使工人之間的任務負荷更加均衡。倣真研究結果錶明：在生產壓力較小的情況下，隻需變彊製節拍為自由節拍，即可有效地提高生產效率；而在生產壓力較大的情況下，變彊製節拍為自由節拍以及閤作均能有效地提高 U 形混流裝配線的生產效率，閤作還能提高工人之間的任務均衡率。

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 worksta-tion was proposed;the influences of workers movement on balance were considered.The basic task di-vision 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 effec-tively when there is higher production pressure,cooperation can improve the task balance rate as well.
