Study on Routing Optimization Model of Container Sea-Rail Intermodal Transport Based on Transit Period

摘要

Container sea-rail intermodal transport is one of the organizational forms of multimodal transport. It refers to providing an integrated container transport service by the effective convergence of water and railway transportation. It has long industry chain, high resource utilization, and good comprehensive benefits. On the basis of considering transit period, this paper proposes a route optimization model of container sea-rail intermodal transport by taking the minimization of total cost as the objective function. At the same time, this paper increases the constraints on transport capacity and transfer capacity. Finally, combining with a numerical example, the model is solved by optimization software. A container transport scheme with relatively least total cost meeting the transit period limit is acquired, which proves the feasibility of the model.
