• This study shows the advantages of job enlargement for aging workers using modern information technology. The concept of this production model, which attempts to balance productivity and workers' individuality, is described. A method using digital simulation for the construction of this production model and an actual case are presented. This production model focuses on manual procedures, and job enlargement thus takes a step back from of the trend towards automation. The actual examination proved the following. The productivity of the new production system became tantamount to that of the conventional flow line system; productivity exceeding 150% in three weeks. With respect to the speed in carrying a screw to a target object, the job-enlargement system requires less time than the flow line-system. This shows that subjects did not tighten screws in the rhythm of the work in the flow-line system. The job-enlargement system allows workers to adjust the production volume per unit time and the motion speed on their own initiative and thus, the workers are thought to be able to carry out tasks at the appropriate rhythm for themselves. Comparison of the motion loci of the flow line system and the job-enlargement system made it clear that when the aging workers used the job-enlargement system there was a smoother loci of motion in carrying the screw to the target (positioning). In the job-enlargement system, the enlarged work contents make it easier for the worker to adapt the speed and locus of the motion to his/her rhythm and it is believed to give the individual a sense of responsibility as well as a sense of achievement and satisfaction in the work. It is presumed that the worker was engrossed in his/her work, and did not find the work tedious.
