Abstract
This research is to study laminate glass production process with the emphasis on the analysis to determine appropriate number of labors. The objectives of this research are to increase labor productivity and overall labor efficiency, and to reduce labor cost. The research process started with studying the production process and number of labors in the current situation in order to find the standard time and the production cycle of the process leading to the calculation of labor productivity, the overall labor efficiency and the labor cost before process improvement. Then, industrial engineering tools, namely, the multiple activity chart and Yamuzumi Chart, were used for considering work load of each employee, resulting in reducing the number of labors. From the work performance process analysis, it was found that the proper number of labors in the First Load and the Splice Room were 2 and 3 persons, respectively. The number of labors was therefore decreased to 7 from 11 persons in aggregate. The study result shows that the labor productivity and the overall labor efficiency increase 57.14 percent and 17.01 percent, respectively, and the labor cost in the laminate glass production process decreases by 581,250 baht per year.
