‘ AUTOMATING WAREHOUSE PROCESSES SPEEDS UP THE PICKING , SCANNING AND MOVING OF GOODS ’ interleaving and slotting can further optimise time consuming picking processes . AGVs can be used to follow operators around the warehouse handling goods , thereby decreasing the walking distance required and the time spent by the operator on each specific task . Finally , RFID tags help track the flow of stock through the warehouse and minimise the need for human intervention when automatically checking stock during the receipt and issue of unopened handling units such as boxes .
