Experimental Study and Statistical Analysis of Human Factors’ Impact in Cell Production System

Yanwen Dong (, Xiying Hao (
Major studies on cell production have put the emphasis on technical factors (machine order/layout, family part grouping, workflow sequence, etc.), it is still insufficient to investigate how human factors affect the efficiency of manufacturing cells. In this paper, we make an experimental study on the human factors’ impact in cell production system. Our study is different from the researchers reported to date in that we carry out a laboratory experiment of cell production to measure the efficiency of the operators in manufacturing cells. Meantime we take a questionnaire to grasp the operators’ aptitude and then make statistical analysis based on the operation times measured during the experiments and the questionnaire result. It was clarified that the efficiency of cell production depends largely on the operators’ aptitude and therefore selection of cell workers is very important for success of cell production.

Keywords: cell production, cellular manufacturing, human factor


What are the differences between SERU and Line-cell Conversion?

Ikou Kaku (, Yang Yu (, Jiafu Tang ( ), Yong Yin (
SERU is a new innovation of manufacturing system developed in Japan. Its essence is dismantling an assembly conveyor line and adopting several mini-assembly units. SERU can increase the productivity and competitive advantages of manufacturers. There are a lot of successful cases had been reported in Japan. However several confusions on SERU, like what is the difference with traditional cellular manufacturing? How to achieve a successful conversion from assembly line? And so on are still inquired. To clarify such confusions a new concept of line-cell conversion had been proposed. In this paper, we summary several research results on line-cell conversion which have been reported in past decade, and clarify several insights on line-cell conversion to compare with SERU. Several future research directions also are discussed to help researchers seed their interesting on line-cell conversion.
