組立課題における作業段取りの効果について

抄録

The purpose of the present paper is to show through experiments how effective ‘work arrangements’ may be when applied to assembling workshops. In experiment 1, a group of 71 junior-high school students made a ‘work arrangement’ before a job, and the quality of the ‘work arrangement’ was found to be positively, though not strongly, related to the quality of the products. In experiment 2, the same subjects were randomly divided into two groups, both doing the same assembling job, but one group used a ‘work arrangement’ while the other did not, so that the effectiveness of the ‘work arrangement’ could be measured. The results were then categorized according to the types of the subjects, namely,‘quick’ type and ‘slow’ type, to see how the types were related to the effectiveness of the ‘work arrangement’, categorization being made on the basis of experiment 1. It was found that the ‘work arrangement’ was effective in reducing work-hour and error incidence, but the effects were obvious only in the ‘slow’ type subjects.
