摘要： 人工作业系统（MOS）是我国中小型企业广泛采取的生产作业模式。在MOS中，员工是决定生产效率的关键因素。分析了生产进度受员工技能差异和变化的影响，以最小化完工期为目标，考虑员工学习效应建立员工指派优化模型。通过一个算例对模型效果进行分析，比较了员工学习效应以及员工异质性对完工期和指派策略的影响。得知员工学习、倦怠效应对完工期及指派策略具有显著影响。对员工异质性的关注有助于缩小理论研究与生产实践之间的差距。与生产实践中的两种现实指派模式——基于初始技能的指派和基于学习率的指派进行对比，表明所建立的优化模型有助于缩短完工期、优化员工配置。进一步分析了指派策略对生产批量的敏感性。结果表明，存在一个指派策略的转折点x*，当批量x<x*时，基于初始技能的指派最优；当x>x*时，基于学习率的指派最优。

Abstract: Manual operation system (MOS) is the general production system mode in the small and medium-size manufacturing enterprises. In MOS, workers are the key factors that determine the production effectiveness. Worker assignment problem is studied to reduce the influence of skills difference and change on production schedule. Assignment optimization models are proposed in considering workers learning effect with completion time as the objective function. The proposed model is verified by a numerical example. The influence of learning effect and workers heterogeneity on completion date and assignment strategy is compared. The results show that the workers- learning effect has a significant impact on the completion date and assignment strategy. The attention to workers- heterogeneity helps to narrow the gap between the theory and production practice. Two practical assignment models-assignment based on initial skills and assignment based on learning effectare compared. Results show that the established optimization model helps to shorten the completion date and optimize worker's assignment. The influence of production batch on different assignment strategy is analyzed. The results show that there is a turning point of assignment strategy x*, when production batch x<x*, assignment strategy based on initial skills is optimal; while production batch x>x*, assignment strategy based on learning effect is optimal.
