In the warehouse management method provided in the embodiments of the present disclosure, the products in the order request are located in the first storage area and the second storage area, the order request is split into two order subtasks by the control server. The first order subtask is executed at the first workstation corresponding to the first storage area, and then the order receptacle is moved by the order receptacle handling device to the second workstation to execute the second order subtask. Alternatively, the second order subtask is executed at the second workstation corresponding to the second storage area, and then the order receptacle is moved by the order receptacle handling device to the first workstation to execute the first order subtask. Further, by a way of order relay, a hit rate of the order request is improved based on the cooperation among the first inventory receptacle handling device, the second inventory receptacle handling device and the order receptacle handling device, thus avoiding the danger caused by the complexity of routes of people and machines, and effectively improving the efficiency of the warehouse management.
In block 602, operations are performed by a control server, the operations including:
In block 604, a specified first inventory receptacle is transported, by the first inventory receptacle handling device, from the first storage area to the first workstation in response to the first handling instruction when the first sub-order is dispatched to the first workstation in the first storage area.
In block 606, a specified second inventory receptacle is transported, by the second inventory receptacle handling device, from the second storage area to the second workstation in response to the second handling instruction when the second sub-order is dispatched to the second workstation in the second storage area.
In block 608, an order receptacle containing a product selected at the first workstation and an order receptacle containing a product selected at the second workstation are transported, by the order receptacle handling device, to a specified confluence location to complete order consolidation in response to the third handling instruction.
Optionally, the first inventory receptacle is a movable inventory shelf, and the first inventory receptacle handling device is a shelf handling robot. The shelf handling robot transports a specified movable inventory shelf from the first storage area to the first workstation in response to the first handling instruction.
Optionally, the second inventory receptacle is an inventory tote, and the second inventory receptacle handling device is a tote handling robot. The tote handling robot transports a specified inventory tote from the second storage area to the second workstation in response to the second handling instruction.
Optionally, the order receptacle is a movable order shelf, an order tote, or an order shelf provided with an order tote.
Optionally, the order receptacle handling device is the shelf handling robot or the tote handling robot.
