Abstract: A system and method for automated materials handling is disclosed wherein palletized goods are stored and retrieved with maximum through-put. This system is particularly applicable for pallets of comparatively large size. In accordance with this system and method, input loads are queued prior to displacement onto a continuous conveyor serviced by a plurality of S/R machines. The queued loads are metered onto the conveyor on a far to near aisle correspondence basis and are simultaneously exchanged for output loads at each of the aisle locations. The method includes compensation for circumstances where outputs exceed inputs and where inputs exceed outputs by empty pallet management.
