Abstract

This research presents the improvement of employees’ efficiency in the automobile part of glass windshield sealer station, a case study of an automotive assembly plant. A combination of the techniques of Man-Machine Chart, 5W1H, and ECRS (Eliminate, Combine, Rearrange, and Simplify) was applied to analyze and to solve the problem of employees’ inadequate performance time comparing to the idle time. The study has resulted in reducing the number of employees from 3 to 1 and can maintain cycle time rate at 120 seconds per item. The work performance has been improved from 58.33 percent to 100 percent. In addition, the results show that the labor costs have been reduced from 54,000 baht/month/shift to 18,000 baht/month/shift.
