Automatic generation of flexible load design

A system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing computing instructions that, when executed on the one or more processors, cause the one or more processors to perform:
• obtaining an original load design for loading a trailer to deliver stacks of pallets to physical stores, wherein the original load design specifies a respective floor spot assignment for each of the stacks in the trailer, and wherein the original load design satisfies center-of-gravity constraints;
• generating fluid groups of the stacks to form an initial fluid grouping of initial fluid groupings, wherein:
• generating the fluid groups is based on one or more containers of the trailer to which the stacks are assigned in the original load design;
• the fluid groups comprise groupings of the stacks that are configured to be loaded interchangeably in different floor spots within each respective fluid group;
• and
• the stacks within a respective set of the stacks for each respective fluid group are interchangeable, to satisfy the center-of-gravity constraints, among respective floor spot assignments for each respective fluid group;
• determining that the fluid groups do not collectively satisfy the center-of-gravity constraints, comprising determining when an upper bound center-of-gravity constraint is satisfied when the stacks of the fluid groups are arranged heaviest rearward in each of the fluid groups;
• until the fluid groups collectively satisfy the center-of-gravity constraints in a final load design, repeatedly:
• determining one or more infeasible groups from the fluid groups, wherein the one or more infeasible groups comprise at least one feasibility check unsatisfied;
• and
• adjusting at least one of the one or more infeasible groups to update the fluid groups;
• and
• outputting the final load design comprising the fluid groups that collectively satisfy the center-of-gravity constraints to cause the stacks to be loaded into the trailer according to the final load design for delivery to the physical stores according to respective delivery routes, wherein the final load design satisfies the center-of-gravity constraints and specifies the respective floor spot assignments for each respective set of stacks for each respective fluid group of the fluid groups.
