Abstract

Background In general, sewing production line distribute the workload in one team in one style. But this study was to divide the workload in two teams(line work-team and time work-team) in women's coats. So this study measured and compared the working time of the sewing process of the two teams, and the result will be utilized as the basis for the standard time setting, capacity grasp, workload assignment, scheduling. Methods The method of study was conducted as follows. 1. After analyzed the sewing method and order, and creates a process sequence table. 2. Working time was measured with a stopwatch the time of each team in accordance with the process order. 3. Standard time and working time was obtained from measured time, and compared the capacity between two teams(line-working and time-worker), and determines a work schedule. Result Work processes of two team consisted that line-worker is 53 processes and time-worker is 48 processes. The calculated results of working and net-working time shown less than the outlier value of time-worker team compared to line-working team, and more focused on the job, the working speed was consistent. In the production capacity, but both teams have the surplus in the preparation & arrangement process, pieces & assemble process is generated overload of –15.9%(line team), -19, 9%(time worker team), so the two piece & assembly teams were required additional work. Conclusion Analysis of the production process of women’s Coats, and measuring the operating time of two team. Time-worker team were to reduce the number of process because of higher skill-level, to maintain a constant flow operation time it was shortened. According to the results, the company distributed to meet the delivery to line-working team assigned brown 242 sheets, and to time-worker team assigned navy color 312 sheets. Piece & assembly processes of both team generated overload. So both of two team performed additional work, and they delivered women’s coats 554 pieces in time. Therefore, this company is considered to identify the production capacity of the worker and team in advance to overcome the short delivery date, and some processes are produced in the subcontractors. And it is required for efficient combination process.
