市场需求的波动、工人流动性的增加和就业实践的变化，以及企业对工人个体差异的尊重程度的提高，导致了制造业企业中效率差异较大的工人在同一条生产线上一起工作的现象。在传统的移动式生产线（TrPL）中，低效率的工人会阻碍高效率工人的工作。为提高由不同效率工人组成的流水线的生产能力，建立了追赶超越机制，实现了流水线生产能力和效率的提高。推导并验证了两个不同效率工人的生产能力计算公式。进行模拟，以分析之间的差异“追赶超越”生产线（COPL），TrPL和经典的“水桶旅”生产线（BBPL）的生产能力，工作时间利用率和设备利用率方面的证明，COPL提供了良好的生产能力和适应工人的差异。最后，统计分析证实，COPL的生产能力、平均工人工时利用率和设备利用率均高于BBPL和TrPL。
Fluctuations in market demands, increased mobility of workers and changing employment practices as well as companies’ increased respect for individual differences of workers have led to the phenomenon that workers with large efficiency differences work together in the same production line in manufacturing companies. In a traditional travelling production line (TrPL), low-efficiency workers can block the work of higher efficiency workers. To increase the production capacity of a travelling line composed of workers with different efficiencies, a chasing-overtaking mechanism was established and used to achieve line production capacity and efficiency improvement. A formula to calculate the production capacity of two workers with different efficiencies was derived and validated. A simulation performed to analyse the differences between the ‘chasing-overtaking’ production line (COPL), TrPL and the classic ‘bucket brigade’ production line (BBPL) with respect to production capacity, working time utilisation and equipment utilisation demonstrated that the COPL provides good production capacity and adaptability to worker differences. Finally, the statistical analysis verified that the COPL has a higher production capacity, average worker working hour utilisation rate and equipment utilisation rate than the BBPL and TrPL.
