Method of managing resources in a warehouse
Described herein is an apparatus and method for selecting a storage location for an item. The method includes obtaining order information for a plurality of previously fulfilled orders, wherein each order includes at least one item. Based on the obtained order information, one or a combination of an affinity value of the item and a popularity value of the item are computed. The method determines available storage locations in a plurality of storage racks, each rack including at least one shelf. Further, the method computes for each available storage location, one or a combination of an affinity score and a popularity score of the storage rack with respect to the item. The method selects the storage location from the available storage locations based on at least one of the calculated affinity score and the calculated popularity score, and instructs a vehicle to store the item at the selected storage location.

8. A non-transitory computer-readable medium storing instructions which when executed by a computer causes the computer to perform a method of selecting a storage location for an item, the method comprising:
obtaining order information for a plurality of previously fulfilled orders, each order of the plurality of previously fulfilled orders including at least one item;
calculating, based on the obtained order information, a combination of (i) an affinity value of the item, and (ii) a popularity value of the item, the affinity value of the item being calculated with respect to at least one other item;
determining a plurality of available storage locations where the item can be stored, each available storage location corresponding to one of a plurality of storage racks and a position on a shelf of the one of the plurality of storage racks;
calculating, for each available storage location, a combination of (i) an affinity score of the storage rack corresponding to the respective available storage location based on the affinity value of the item, and (ii) a popularity score of the storage rack corresponding to the respective available storage location based on the popularity value of the item;
selecting the storage location from the available storage locations based on a combination of (i) the calculated affinity score of the storage rack corresponding to the selected storage location, and (ii) the calculated popularity score of the storage rack corresponding to the selected storage location; and
instructing a vehicle to store the item at the selected storage location.
9. The non-transitory computer-readable medium of claim 8 , wherein the affinity value of the item calculated with respect to the at least one other item indicates a likelihood in which an order of the plurality of previously fulfilled orders includes the item and the at least one other item, and the popularity value of the item indicates a number of times the item is retrieved for the plurality of previously fulfilled orders.
10. The non-transitory computer-readable medium of claim 8 , wherein the popularity score of the storage rack corresponding to the respective available storage location is calculated as an average of the popularity values of items stored in the storage rack.
11. The non-transitory computer-readable medium of claim 8 , wherein the step of selecting the storage location comprises:
selecting the storage location based on a difference between the popularity score of the storage location and the popularity value of the item.
12. The non-transitory computer-readable medium of claim 8 , wherein the affinity score of the storage rack with respect to the item is calculated as an average of affinity values of each combination of the item with items stored in the storage rack.
13. The non-transitory computer-readable medium of claim 8 , the method further comprising:
generating, based on dimensions of the item, a cuboid that completely encapsulates the item, a volume of the generated cuboid indicating an amount of space required to store the item.
14. The non-transitory computer-readable medium of claim 13 , wherein the plurality of available storage locations is determined based on a predetermined number of orientations of the generated cuboid.
15. An information processing apparatus, comprising:
a processor configured to:
obtain order information for a plurality of previously fulfilled orders, each order of the plurality of previously fulfilled orders including at least one item,
calculate based on the obtained order information, a combination of (i) an affinity value of the item, and (ii) a popularity value of the item, the affinity value of the item being calculated with respect to at least one other item;
