ANALYZING THE DISTURBANCES IN GARMENT MAKING LINES

Effective use of production resources is of big importance for both production and serving sectors. Disturbances of manufacturing systems have a negative impact on the performance of production and result in productivity losses. Aim of this study is to analyze the causes of disturbances and to investigate the effects of production disturbances to efficiency of manufacturing times. For this purpose, three case studies from apparel plants which are founded in city of Izmir were examined. Data of the study were obtained using the distribution time method which is divided according to random time plan. The method used in this study is offered by The REFA- Association for Work Design/Work Structure, Industrial Organization and Corporate Development. Eighteen different machines operating in garment making lines of the plants were used in time measurement. Selected sewing machines should represent all the operations in production was targeted. These sewing machines also represent workstations to collect data for the study. In this study, production period which is 10800 minute was used for each plant According to the results obtained, waiting times, correcting the seam faults and breakdown of machines are the major causes of disturbance. These disturbances reduce the efficiency of manufacturing time and may upset production schedules during execution.
