Study on work improvement in a packaging machine manufacturing company

This paper studies the improvement of production efficiency and balance rate of the manual assembly line in a packaging machine manufacturing company. Modular arrangement of predetermined time standards (MODAPTS) method is used to obtain time values for elements and for entire operations of the manual assembly line. Also the ECRS four principles (eliminate, combine, rearrange and simple) are used to minimize the idle time at every station or the percentage of line balance loss. In order to verify the results that were obtained from the generated line-balancing pre- and post-, Witness simulation software is used to estimate the output. Simulation results showed that productivity increases about 41.72% higher than the current situation.
