Abstract: Transportation plan adjustments based on recommended shipping packages may utilize a shipment data model for a facility that is updated with cubic volumes of recommended packages for received orders. The shipment data model may also be updated with the cubic volumes of the packages that are actually used to pack the orders and transportation utilization data such as assignment of packages to particular transportation resources. A transportation plan may be updated based on the updated shipment data model and transportation utilization data such as which transportation resources have left the facility and how much of the available cubic volume of the resource was used when the resource left the facility. The transportation plan may be updated at times associated with transportation resource change deadlines from one or more transportation resource providers. Adjustments to previously scheduled transportation resources may be made based on the updated transportation plan.
