Vehicle Dispatching Under the Shortest Path and Port Centralization

The vehicles of the distribution centers affiliated with a port are brought under the condition of unified dispatch, under load vehicles transporting the goods in distribution centers which they pass, and the transport capability of vehicles and the total amount of goods in each distribution center to be considered. The problem is transformed into the transportation problem, and a mathematical model is established. An algorithm is proposed under the condition of transporting the goods in distribution centers if the vehicles pass. A computational example shows the method in this paper can reduce transportation costs.
