(a) The time spent by AGV (Automated Guided Vehicle) for
simultaneously unloading containers using a sorter with infinite
capacity.
(b) The time spent by 4 AGVs to unload 100 pallets from 5
containers versus the pallet processing time at the sorter.
(c) The number of pallets unloaded per minute versus the number
of AGVs for different numbers of containers.
