A system including 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 operations: receiving a load design for loading a trailer to deliver orders; generating an initial grouping comprising stacks of pallets that are configured to be loaded interchangeably among respective floor spot assignments on the trailer; iteratively adjusting at least one of the stacks of pallets within the initial grouping to satisfy at least a center-of-gravity constraint in a final load design for the trailer; and outputting the final load design comprising the initial grouping to cause the stacks of pallets of the initial grouping to be loaded into the trailer according to the final load design. Other embodiments are described.

Automatic generation of flexible load design

A system including one or more processors and one or more non-transitory computer-readable media storing computing instructions configured to run on the one or more processors and perform: generating a feasible dock-out plan designed to deliver one or more orders to one or more physical stores based on a feasible route plan by: generating a preliminary dock-out time boundary based on one or more delivery time windows; determining an earliest dock-out time based at least in part on the preliminary dock-out time boundary and a backward search; and determining a latest dock-out time based at least in part on the preliminary dock-out time boundary and a forward search; and transmitting a range of dock-out times comprising (i) the earliest dock-out time and (ii) the latest dock-out time to a user. Other embodiments are described.

Flexible dock-out time

Systems and methods including one or more processors and one or more non-transitory storage devices storing computing instructions configured to run on the one or more processors and cause the one or more processors to perform receiving one or more orders comprising a list of one or more pallets; grouping each pallet of the one or more pallets into one or more groups using one or more respective qualities of each respective pallet; for each group of the one or more groups, building one or more stacks of pallets using at least three different stacking models; selecting a final stack list of a model of the at least three different stacking models having a lowest number of stacks; and optimizing the final stack list using a probabilistic model. Other embodiments are disclosed herein.

Systems and methods for vehicle routing

A system including 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, perform certain acts. The acts can include obtaining an original load design for loading a trailer to deliver stacks of pallets to physical stores. The load design specifies a respective floor spot assignment for each of the stacks. The original load design satisfies center-of-gravity constraints. The acts also can include generating fluid groups of the stacks to form an initial fluid grouping. The acts additionally can include determining that the fluid groups do not collectively satisfy the center-of-gravity constraints. The acts further can include until the fluid groups collectively satisfy the center-of-gravity constraints, repeatedly determining one or more infeasible groups from the fluid groups, and adjusting at least one of the one or more infeasible groups to update the fluid groups. The acts additionally can include outputting a flexible load design comprising the fluid groups that collectively satisfy the center-of-gravity constraints. Other embodiments are described.
