Organization Optimization Model of Tramp Container Sea-rail Intermodal Transport Trains

Lei Tang, Yifei Zhang*, Mengfan Sun

Abstract


In view of the single regular organization mode of container sea-rail intermodal train and the long storage time in ports, to organize
tramp sea-rail intermodal train as a supplement to regular organization is of great significance to improve the efficiency of transport services.
A nonlinear mixed integer model is proposed to maximize transportation profits. Variables of train and cargoes are optimized simultaneously,
including the number, transport capacity, timetable and path of tramp sea-rail intermodal freight train, containers selected and assigned to the
different train. The case study indicate that seven tramp freight trains are organized to transport 1,194 containers unloaded in the Dalian port.
The method proposed has theoretical reasonableness and practical feasibility.

Keywords
