Abstract

Less than truckload carriers collect freight from various shippers and consolidate that freight onto enclosed trailers for linehaul to the delivering terminal or to a hub terminal where the freight will be further sorted and consolidated for additional linehauls. Large distribution center (DC) often has more than 100 scheduled truck service from/to other centers. So it needs many freight slots for shipment storage, loading and unloading. For each truck service, there are several shift during one day. In the scheduled truck service network, each Origin-Destin (OD) in a specifc time period has more than one paths to choose. Currently, freight slots have fixed allocation according to the destination of the truck service, which results in much moving cost for shipment inside the DC. Actually, we find that: Shipments may choose other paths than shortest path due to the service capacity, but it will never be moved to opposite direction. Plus, due to level of service, there is less than 3 paths for one specific OD. Plus, freight slots can be dynamically assigned to truck services according to their timetable. Basic idea of this disclosure is dividing the whole time-space network into several smaller pieces according to OD pattern and allocate freight slot proactively in order to decrease the moving cost inside distribution center.
