Order picking process is the most time consuming activity in a warehouse which increases the warehousing cost. To address such inefficiency, a variety of automated systems have been developed. Among them, the A-Frame System is an automated order-picking equipment which is used in a warehouse to handle medical supplies and tobaccos. But in a replenishment area of A-Frame, the workers manually perform the task yet. In this reason, there’s a need for research to increase the utilization of workers.
This paper analyzes the replenishment tasks by comparing a moving distance between a single-layer A-frame System and a multi-layer A-frame System. To compare the distance, we conduct simulation study considering operational environment and real world order information acquired at a tobacco warehouse.
