Cellular manufacturing has become an integral part of lean manufacturing systems; more and more attentions have been paid to cellular manufacturing. Although the quality and productivity of cell production systems depends largely on operators ’skill and other human factors, it is still insufficient to investigate how human factors affect manufacturing cells. Here, we apply structural equation modeling to analyze the impact of human factors on productivity of cellular manufacturing. We design a laboratory experiment of cellular manufacturing to measure the efficiency of the operators in manufacturing cells and meanwhile, conduct a questionnaire to grasp the operators ’aptitude. A covariance structure model is constructed based on the experiment data and the questionnaire ’s answers, the potential causal dependencies between the productivity and human factors can be showed graphically and quantitatively through the pass diagram. Our results have showed that operators ’aptitude has significant e ffects on cell ’s efficiency and the impact of operators ’aptitude is largely stronger than the learning effect.
