자동차 조립작업자들의 직무순환에 따른 만족도 및 생산활동 지수에 관한 연구

Abstract

The purpose of this study is to identify the types and features of job rotation being operated in a motor company and to analyze productivity, job satisfaction, quality and contribution to accident prevention by job rotation system. The types of job rotation have been classified according to the range of rotation and its cycle. Also, the features of the favorable rotation types were examined by the worker's age and their types of tasks. The results show that workers prefer broader ranges and slower cycles of rotations as they age. Moreover, older workers tend to show an increase in the preference of participating in job rotations. The job rotation in this study has been carried out by voluntary decision of workers. Workers under 40 prefers to speed up the rotation cycle to reduce repetitive use of the same parts of the body also to prevent tediousness, and musculoskeletal disorders. On the other hand, workers over 40 with rich experience tend to prefer rather slow rotation cycle generally showing a high satisfaction, and having low accident victims, and musculoskeletal disorders. Accordingly, the job rotation in a motor assembly operation, the satisfaction can be increased by expanding rotation range and by multi-functionality of workers, and also tediousness and tiresome can be prevented. If there is a limitation to secure diversity of rotation range, it is expected that the problems can be solved by suitably controlling the rotation cycle. This study expects that job rotation range and cycle can heighten satisfaction and reduce fatigue which lead to high productivity and quality and low accident. Moreover, it may contribute to cope with the placement of personnel by multi-functionality effectively in the global market economy system. And the result of this study is expected to be applied as fundamental data to job design.
