Abstract

Load imbalances among Material Handling (MH) operators in the automotive manufacturing industry may result in overload or idle conditions, thereby disrupting material supply and delivery accuracy. This study measured the cycle of time standard of MH activities using the Standardized Work Type 3 (SW Type 3) method, analyses workload distribution through Workload Analysis and the Yamazumi Chart, and designs a feasible workload-balancing scenario for automotive component manufacturing companies. Data were collected via time studies with five repetitions per activity in the Finished Goods (FG), Delivery, and Brake Assembly/Drum in Hat (BA/DIH) areas. Results indicated that the FG area was overloaded, with utilization rates of 115.7–120.0% of the available 480 minutes per shift. The Delivery area experienced critical overload, with utilization rates ranging from 177.0% to 207.8%. In contrast, the BA/DIH area exhibited a maximum workload gap of 70.9 minutes per shift, despite all operators remaining below the available time. The job-balancing scenario, implemented through the redistribution of Supply Empty Box activities, reduced the workload gap among operators by 72.2%, ensuring all operators remained within their available time.
