Major studies on cell production have put the emphasis on technical factors such as machine order / layout, family part grouping, work?ow sequence, etc., it is still insufficient to investigate how human factors affect the performance of production cells. In order to assess precisely the impact of workers aptitude on productivity, we have made a series of experimental studies and questionnaire analyses. However, because the workers participated in all of these experiments and questionnaires were university students, it is necessary to clarify whether the results of our experiments and questionnaires obtained from the student workers can also be ?tted to general workers. In this paper, we hire 40 workers from the general public and conduct the cell production experiment. Then, we make several statistical comparisons on the differences in working performance and answers to questionnaire between student workers and general workers. We also extend our studies through investigating the impact of workers age and their gender on the performance of production cells. It was clari?ed that the assembly times of student workers are generally shorter more than 10% than the general workers; in contrast, there are not signi?cantly large differences in the answers to the questionnaire between the student workers and the general workers. Meanwhile, the workers gender and age have signi?cant impact on the performance of production cells.
