• wherein the sorting area is divided into a plurality of sub-areas, each sub-area is deployed with a plurality of supply stations and a plurality of delivery openings, and one delivery opening corresponds to one destination;
• wherein, the control server is configured to:
• determine a target delivery opening corresponding to a destination of an item to be sorted according to destination information of the item to be sorted;
• determine a target sub-area where the target delivery opening is located among the plurality of sub-areas of the sorting area;
• select a target supply station in the target sub-area by calculating a total delivery distance of all items to be sorted in the item transfer container corresponding to a respective one of different supply stations of the target sub-area;
• and selecting the target supply station of the plurality of supply stations of the target sub-area based at least in part on the total delivery distance;
• and
• assign a delivery task to a target sorting robot among the plurality of sorting robots;
• the target sorting robot is configured to:
• after the item to be sorted is transported to a supply station in the target sub-area, in response to the delivery task, retrieve the item to be sorted from the supply station where the item to be sorted is located;
• transport the item to be sorted to the target delivery opening in the target sub-area for delivery;
• wherein the total delivery distance is a total walking distance of each sorting robot while delivering each item in the item transfer container from the supply station to a corresponding delivery opening.
