关于单元生产的主要研究侧重于机器订单/布局、家庭零件分组、工作流程顺序等技术因素，然而，关于工人的能力如何影响其在生产单元中的表现的研究仍然不足。为了找出工人的能力与其在电池生产中的表现密切相关，我们设计了一个实验室实验，对工人进行了日本通用能力测验(GATB)的11个纸笔测试，并测量了他们的7个与工作相关的能力。我们特别注意检测GATB分数和细胞生产实验结果中的异常值，然后检验工人的GATB分数和他们的表现之间的部分相关性。由于GATB得分不能直接衡量工人在生产单元中完成装配任务的能力，我们利用主成分分析得到了与工人在单元生产中的表现显著相关的成分得分。因此，我们可以应用这个成分分数来衡量工人在单元生产中对组装任务的能力。
Major studies on cell production have placed an emphasis on technical factors such as machine order/layout, family part grouping, work-flow sequence, etc. However, there have still been insufficient investigations as to how workers’ aptitudes affect their performance in production cells. Intending to find the worker’s aptitude closely relating to her/his performance in cell production, we design a laboratory experiment, and administer 11 paper-and-pencil tests of the Japanese General Aptitude Test Battery (GATB) to the workers and measure their seven work-related aptitudes. We pay special attention to detecting outliers in the GATB scores and the cell production experiment results, and then examine the partial correlations between the workers’ GATB scores and their performance. As the GATB scores can’t directly measure a worker’s aptitude towards the assembly tasks in production cells, we make use of principal component analysis and obtain a component score that correlates significantly with the workers’ performance in cell production. As the result, we can apply this component score to measure a worker’s aptitude towards the assembly tasks in cell production.
