In
the cited figure, we can observe that the throughput for five
AGVs is about 2,8 pallets per minute while using more than
five AGVs we can obtain only little improvements. In fact,
increasing the number of AGVs the throughput goes towards
three (3,1 pallets per minute with 8 AGVs). This diagram
highlights once again that adopting five AGVs is a reasonable
choice.
