订单式生产（ MTO）人工作业系统（ MOS）是我国中小制造企业广泛采用的生产系统模式。在MTO/MOS中，一线员工生产技能对生产绩效具有直接的影响。随着重复操作次数的增多，员工的生产效率不断提高，即产生学习效应。本文考虑员工学习效应来优化一线员工的配置，强调员工初始技能和学习能力的个体差异对完工期的影响，以期缩小理论研究与生产实践之间的差距。本文首先提出一个基于员工初始技能、员工的学习能力、工艺难度和订单批量的员工技能动态变化函数。然后，以最小化完工期为目标，建立一个优化模型。由于员工指派问题属于“完全NP-Hard”问题，为了求解本文所提出模型，本文提出Bootstrap方法对问题进行求解。最后，基于一个算例分析，验证该模型及算法的有效性。

MTO( Make-To-Order) and MOS( Manual Operation System ) is the general production system model of the small and medium manufacturing enterprises .The worker ’ skills have an important influence on the perform-ance in such a system .With the growing in times of repetition , learning effect happens and workers ’ efficiencies continuously improve .We propose an optimization model of the front-line workers ’ Assignment considering learning effect , paying full attention to the individual difference in order to narrowing the gap between theory re-searches and production practices .Taking the lead time as the objective function , the model is based on work-ers’ previous experience, learning ability, technology difficulty and batch size .Due to workers’ assignment is NP complete problem , the Bootstrap approach to solve the problem is proposed .A case study indicates that the proposed model can provide a promising worker assignment approach and the proposed algorithm is effective for combinational optimization problem .
