Abstract

The disclosure describes, in part, a system and method for improving the stacking of containers on or in a transportation unit. In some implementations, a stacking configuration may be planned that identifies containers and a position for those containers in the stacking configuration. The stacking configuration may be planned based on dimension values of the containers such that when stacked the stacking configuration remains stable. In addition, to improve the efficiency at which containers may be stacked, the disclosure describes that containers and/or the picking of items for those containers may be sequenced so that the containers, when packed and routed, arrive in a manner that allows efficient stacking.

First claim

What is claimed is:

1. A computer-implemented method for planning a stacking configuration, comprising:
under control of one or more computing systems configured with executable instructions, identifying a container, the container having container dimension values;
planning a stacking configuration for a transportation unit based at least in part on the container dimension values, the stacking configuration identifying a location and position of the container;
sequencing at least one of a picking operation, a sorting operation or a packing operation based at least in part on the stacking configuration, the sequencing comprising:
sequencing steps associated with at least one of the picking operation, the sorting operation, or the packing operation;
sequencing an order of at least two of the picking operation, the sorting operation, and the packing operation; or
sequencing the steps associated with at least one of the picking operation, the sorting operation, or the packing operation, and sequencing the order of at least two of the picking operation, the sorting operation, and the packing operation;

wherein the at least one of the picking operation, the sorting operation or the packing operation are performed prior to routing to a stacking operation at the transportation unit, the container is associated with an item package, and the picking operation includes picking items of the item package for the container, the sorting operation includes sorting items of the item package for the container, and the packing operation includes packing items of the item package into the container; and
causing the container to be stacked at the transportation unit based on the stacking configuration.

2. The computer-implemented method of claim 1 , wherein the stacking configuration includes a position of a plurality of containers at the transportation unit.

3. The computer-implemented method of claim 2 , wherein the stacking configuration is designed to provide a stable environment of the plurality of containers based on a position of each of the plurality of containers in the stacking configuration.

4. The computer-implemented method of claim 1 , wherein planning a stacking configuration includes:
identifying a stacking configuration for the transportation unit; and
re-planning the stacking configuration to include the container.

5. The computer-implemented method of claim 4 , wherein re-planning the stacking configuration includes re-planning a position of at least one planned container associated with the stacking configuration.

6. The computer-implemented method of claim 5 , wherein re-planning a position of at least one planned container includes excluding the planned container from the stacking configuration.

7. The computer-implemented method of claim 1 , wherein the stacking configuration corresponds to a stack quadrant associated with the transportation unit.

8. The computer-implemented method of claim 7 , wherein the transportation unit includes a plurality of stack quadrants, each stack quadrant having a planned stacking configuration.

9. A non-transitory computer-readable storage medium storing instructions for planning a stacking configuration, the instructions when executed by a processor causing the processor to at least:
identify a container;
plan a stacking configuration for a transportation unit, the stacking configuration identifying a location and a position of the container among a plurality of containers;
sequence at least one of a picking operation, a sorting operation, or a packing operation based at least in part on the stacking configuration, the sequence comprising:
sequence steps associated with at least one of the picking operation, the sorting operation, or the packing operation;
sequence an order of at least two of the picking operation, the sorting operation, and the packing operation; or
sequence the steps associated with at least one of the picking operation, the sorting operation, or the packing operation, and sequence the order of at least two of the picking operation, the sorting operation, and the packing operation;

wherein the at least one of the picking operation, the sorting operation, or the packing operation are performed prior to routing to a stacking operation at the transportation unit, the container is associated with an item package, and the picking operation includes picking items of the item package for the container, the sorting operation includes sorting items of the item package for the container, and the packing operation includes packing items of the item package into the container; and
cause the container to be stacked at the transportation unit based on the stacking configuration.

10. The non-transitory computer-readable storage medium of claim 9 , the instructions when executed by the processor further causing the processor to at least:
confirm a placement of the container corresponds with the location and the position of the container in the stacking configuration.

11. The non-transitory computer-readable storage medium of claim 9 , wherein the stacking configuration is designed to provide a stable environment of the plurality of containers based at least in part on a position of each of the plurality of containers in the stacking configuration.

12. The non-transitory computer-readable storage medium of claim 9 , wherein the instructions when executed by the processor further causing the processor to at least:
identify a stacking configuration for the transportation unit; and
re-plan the stacking configuration to include the container.

13. The non-transitory computer-readable storage medium of claim 12 , wherein the re-plan of the stacking configuration includes a re-plan of a position of at least one planned container associated with the stacking configuration.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the re-plan of the position of at least one planned container includes excluding the planned container from the stacking configuration.

15. A computing system, comprising:
one or more processors; and
a memory coupled to the one or more processors and storing program instructions that when executed by the one or more processors cause the one or more processors to at least:
identify a container;
plan a position in a stacking configuration for the container, the stacking configuration identifying a location and a position of the container among a plurality of containers;
sequence at least one of a picking operation, a sorting operation, or a packing operation based at least in part on the stacking configuration, the sequence comprising:
sequence steps associated with at least one of the picking operation, the sorting operation, or the packing operation;
sequence an order of at least two of the picking operation, the sorting operation, and the packing operation; or
sequence the steps associated with at least one of the picking operation, the sorting operation, or the packing operation, and sequence the order of at least two of the picking operation, the sorting operation, and the packing operation;

wherein the at least one of the picking operation, the sorting operation, or the packing operation are performed prior to routing to a stacking operation at a transportation unit the container is associated with an item package, and the picking operation includes picking items of the item package for the container, the sorting operation includes sorting items of the item package for the container, and the packing operation includes packing items of the item package into the container; and
cause the container to be st
