Assembly line balancing in an electronics company using simulation approach

Abstract

One of the efforts company did continuously to compete was to reduce waste or anything that is not adding value to products such as waiting activity that cause unbalance of workload between workstations on a production path. This condition resulted in idle work station, accumulation of intermediate goods, and low work station utility. Companies finds an unbalance workload. This work station are apparently have to wait in a given time after workstations does behind it finished. For that reason, this study aims to balance the workload between workstations and increase the company production capacity. This research uses simulation approach by modelling the initial production with software promodel and evaluate performance the the initial production with an indicator current content, output, and average time in operation. The performance of the initial production line model was the smoothness index of 2007.5, the current content of 10 units, the output of 34 units, and the average time in operation of 35.19 minutes. The alternative model of the selected production trajectory is due to excel in four track performance factors is lowest current content (1 unit), highest output (48 units), lowest smoothness index (461,8) and highest production capacity (9,12 unit/hour).
