To solve the traffic congestion in the port and alleviate the interruption phenomenon of urban collection and distribution,it has become a new trend to construct the future logistics system with the thinking of three-dimensional traffic.In view of above problems,the research of key technologies of intelligent air rail collection and distribution system is carried out.The air rail transport process is designed and ESIA method is adopted to simplify the transport path and splice the process.The adaptive dynamic ant colony algorithm is used to solve the reconstruction,integration and iteration difficulties of the air rail collecting and distributing system and the existing system of the wharf.Mixed integer programming with linear constraints and improved chaotic PSO algorithm are used to solve problems of empty rail box selection and path coordination.By designing the overall structure of the system and analyzing function modules of each subsystem,a universal system implementation scheme is obtained.
