Railway transportation plays an important role in the enterprise logistics part, and shoulders the security of production. Enterprise railway transportation works mostly with artificial job scheduling in our country for a long time, resulting in low efficiency, logistics and transportation is not timely. With the development of economy, enterprises expands the production scale, the backward scheduling mode can’t meet the growing production and transportation requirements of enterprise. Therefore it makes so much sense to improve the efficiency of enterprises railway transportation to research on enterprise railway job intelligent scheduling, realize the automatic compilation and optimization of operation plan.This thesis studies several key problems of Railway scheduling Plan Intelligent dispatching system, a method of intelligent scheduling based on ant colony algorithm aiming at the core of system is put forward,this method abstracts the operation of trailer as nodes for ant colony searching, it transforms the railway scheduling as a search problem of the ant colony algorithm, and select the optimal plans of ants as scheduling plans through cost comparison, the method is applied to the enterprises Railway scheduling Plan Intelligent dispatching system successfully.Path searching algorithm of Industrial Railway Logistics is the basic function of industrial railway intelligent scheduling system, and its efficiency and its target path is directly related to the efficiency and accuracy of the transportation plan. Based on the analysis of railway station, the thesis abstracted station as graph structure, and the topology model is established based on the structure of railway station. Path searching algorithm is proposed based on the defining directed graph mode, to complete the path search function.Vehicle location information is the foundation of the transportation organization and scheduling within the enterprise railway transportation, only grasping the position information of all vehicles at the station of enterprise railway accurately and timely, can enterprises realize the normal railway transportation. The thesis proposes an algorithm to trace the vehicle position, which is based on railway transportation operation plan generated by intelligent dispatching system of railway transportation.The development of the enterprise railway scheduling plan of intelligent dispatching system is developed based on the research above. The thesis gives the implementation framework and the main modules of the system which verifies the practicability of the theoretical research above and project feasibility.
