As container yards of integrated sea-rail intermodal transportation rely on trucks for horizontal transfer operations, in order to shorten the internal transfer time for the yards and improve the utilization rate of trucks, a new idea of joint scheduling of railway and port trucks was proposed. Based on the orientation to sea-rail intermodal transport integration, this paper, rather than attempted to distinguish between railway and port trucks, invested in purchasing shared trucks through port-rail platform companies for any level of transportation task of the entire intermodal transportation organization, to optimize the sea-rail transportation and loading process and shorten the container circulation time in the port, thus improving the utilization rate of trucks. This paper established an integer programming model with a view to overall minimum of truck scheduling cost, empty vehicle operation cost, and time window penalty cost as the optimization objective. And the genetic algorithm was written using MATLAB software to solve the truck scheduling model, with further research and analysis conducted on examples to obtain the optimal truck joint scheduling plan. Besides, a special design has been made for the individual encoding method of the genetic algorithm to make the algorithm more adaptable to the problem. It is concluded through comparative experiments that the joint scheduling scheme has reduced transportation costs to a certain extent, proving its feasibility and superiority.
