Abstract: In the system of container multimodal transportation, the way of inland transportation and path selection have significant impacts on doortodoor transportation. To rationally organize container multimodal transportation, a mixed integer programming model with time constraint is developed. Aiming at minimizing the total cost, the model considers the node operation randomness’ influences on the path and modes choice. Then, the optimal model is turned into a shortest path model with time constraint by chat transform. The numerical results show that the solved path is reasonable and operable in aspects of time and cost. It provides a useful tool for path choice of multimodal transport.

Key words: integrated transportation, path optimization, integer programming, multimodal transportation, container transportation
