Study On Theory And Methods Of Emu Routing Scheme Problem

EMU has been widely used in our existing line of Route passenger line, high-speed rail and intercity rail, and with the reconstruction of existing railway speed passenger line and high-speed rail rapid development of the EMU’s operating range will be gradually to expand. In addition, the acquisition cost of EMU, maintenance and overhaul costs, a larger proportion in China’s investment in railway infrastructure, the reasonableness of its use and maintenance will directly determine the cost of production, is the rail transport organizations face important practical problem. Therefore, the preparation of studies of the EMU Routing Scheme to become a key issue for the field of rail transport organizations.The papers draw on existing research, optimization ideas, improve the model and algorithm and computerise automatic preparation as the goal to study the routing of the current circumstances in China EMU planning. The following major elements:1. An analysis of China’s EMU Routing Scheme prepared by the technical processes, influencing factors and modeling, pointed out that China’s EMU Routing Scheme should be selected preparation steps, use patterns and inadequacies. Commonly used modeling methods and algorithms analysis, to clarify and broaden the mathematical methods of the EMU routing optimization planning.2. The paper determins the optimization ideas and relevants parameters of the dynamic vehicle routing plan prepared and builts on the basis of the. planning of the EMU routing optimization model, the model highlights consider appropriate adjustment of train operation diagram (do not change the running between the train optimized on the basis of the order), then ant colony algorithm optimization algorithm to study and design of improved ant colony algorithm to solve the model. The last picture shows the example to Jinan to Qingdao train operation is verified to prove the model and algorithm has some availability.3. Discusses the design of E EMU Routing Scheme system, the paper based on m EMU Routing Scheme preparation processes and user needs, system functionality, overall design, function, structure and key technical point of view of the system the necessary design and analysis.
