摘要： 本文研究了考虑工人装配水平差异、不同工位之间可以流动分配的装配线工人优化调度，在确定混流装配线的排序后，装配工人在其最擅长的工位工作，在完成本工位的工作后参与其他工位的装配工作，定义相关的优化因素变量和约束条件，建立了考虑工人工位效率差异且可流动分配的混流装配线工人优化数学模型。采用削峰填谷算法和多种群移民算法进行工人的调整和均衡优化，利用一个三层神经网络对削峰填谷的工位进行评估选择，得到工人的最优分配方案，最后通过Matlab对举例进行了验证。算例优化后，减少了2名装配工人，并提高了装配线的平衡率。

Abstract: The optimal workers scheduling of assembly line considering the differences in worker assembly levels and the flow distribution between different workstations was analyzed. After determining the sort of mixed flow assembly line, the assembly worker worked in the workstation where she/he was good at and took part in the assembly work of other stations after completing the work in this workstation. An optimized mathematical model of mixed-flow assembly line workers considering the difference in workstation efficiency and flow distribution was established after the definition of the relevant optimization factor variables and constraints. The peak sharpening algorithm and multiple population migration algorithm were adopted for the adjustment of the workers and balance optimization, and then a three-layer neural network to evaluate peak cutting the location choice was used to obtain the optimal allocation of workers. Finally, an example was given to verify the listed model with Matlab, and two assembly workers were reduced and the assembly line balance rate was increased.

Key words: mixed flow assembly, worker optimization, efficiency difference, flow distribution
