This study deals with a long-term design issue of dynamic line balancing (DLB) when work- sharing is allowed among stations. The work-sharing can be implemented by floating works or floating workers where a portion of tasks or workers is shifted to the succeeding station respectively. We suggest a mathematical model to minimise line cycle time in floating-worker environments. The line considered in this study is a 2-skill chaining line where each worker can help only the immediately downstream station. We suggest a closed form condition of balanceable floating-worker lines (FRL) in case of straight line configuration and U-shaped line configurations along with a comparison with floating-work lines (FKL). We could prove that the FRL is more efficient than the FKL as long as the floating line is balanceable. In case of a U-shaped line, we find that both the FKL and the FRL are always balanceable with the minimum cycle time, which is the total task time divided by the number of stations.

本研究涉及当站点之间允许工作共享时动态线路平衡 (DLB) 的长期设计问题。工作分担可以通过浮动工作或浮动工人来实现，其中一部分任务或工人分别转移到下一个工位。我们建议使用数学模型来最小化浮动工人环境中的生产线周期时间。本研究中考虑的生产线是 2 技能链式生产线，其中每个工人只能帮助紧邻下游的站点。我们建议在直线配置和 U 形线配置的情况下平衡浮动工作线 (FRL) 的封闭形式条件以及与浮动工作线 (FKL) 的比较。只要浮动线是可平衡的，我们就可以证明 FRL 比 FKL 更有效。在 U 形线的情况下，
