The container is the standardization. One container per unit of product. Containers ("bins") dimensioned in multiples of some standard unit that evenly divides a grid system on a rack. Stuffing looks like "a pallet of identical goods appears on one side of your workspace and 150 individual 100mm x 200mm x 400mm bins appear on the other side and the job is to put A into B". Storage operations look like they do now using the robot racks. Emptying looks like "Three bins of various sizes shows up on one side and a cardboard box appears on the other side". You divide the tasks up and have a different machine or human for each. The benefit is you always have a reliably identical picking and stuffing task per item, and there is never a bin of remainder items that has to be pushed back into the system. The cost is lowered storage efficiency. You don't even have to break a pallet at a DC, you can design for distribution of bins (at a higher transport cost).
