Abstract:
This Thesis has the main objectives to study problem of garment manufacturing in sewing room department. Eighty percent of all operators in garment manufacturing will be sewing workers. From the study, it is revealed that problem has effect to low productivity in sewing room department. Almost problems are happened by unbalancing production lines are generated waiting, delay time, bottleneck and work in process. And the unbalancing problem caused from un-balance man power plan, un-equal skill of operators and long distance of machine layout and work flow. The productivity improvement in garment manufacturing is used industrial engineering technique to improve production line which started by job improvement via work study method and ECRS principles to eliminate unnecessary activities and reduce cycle time in each operation, operation breakdown analysis for balancing man-power to achieve target and changed new machine layout and work flow. The results of productivity improvement in garment manufacturing are the production is increased from 0.67 unit/person/hour to 0.92 unit/person/hour, efficiency of line balancing increase form 52.77% to 84.11%. Otherwise sewing process is reduced from 72 processes to 68 processes, and the transportation distance is reduced from 105 meters to 87 meters.
