Optimization Research On Arrival.Departure Track Utilization Plan For Dongsheng Station

With the rapid development of railway transportation industry in China,the transportation volume and the task of trains to be received and sent becoming more and more daily.Arrival-departure track is one of the key facilities for station to receive and send trains and organize trains to conduct other station jobs.It is the importation resources to guarantee the arrival-departure track working efficiency and the through capacity of trains.Drawing up the operation scheduling can improve the working performance of the station,formulating the arrival departure track utilization plan is the key and the difficult point.Working out a reasonable arrival-departure track utilization plan is a urgent problems for station to make trains safely and efficiently finished jobs.Arrival-departure line is the most basic element of train operation in a station.Therefore,it is helpful to set up reasonable operation plan of arrival-departure line for improving railway transportation efficiency,reducing train delays and improving economic benefits of train operation.Optimizing the application plan of arrival and departure lines of railway stations can promote the progress of theoretical research on Intelligent Railway stations,improve the theoretical system of optimization plan of arrival and departure lines,and provide strong support for more intelligent dispatching of railway stations,which has certain theoretical value.This paper took the arrival-departure track utilization plan for Dongsheng station as goals.On the basis of analyzing the operation system and the through capacity for Dongsheng station,the optimization methods of arrival-departure utilization plan for Dongsheng station were researched.Hoping this research can provide suggestions for the further optimization of enterprise decision making.The main research work are summarized as follows:(1)This paper analyzed the background and significance of the research,summarized the research results of scholars at home and abroad in the problems of arrival-departure track in recent years.According to the actual situation of arrival-departure track utilization plan for Dongsheng station,formulated and designed the main research contents and technical route.(2)The operation system and the operation process of Dongsheng station were researched.The main operation equipment and operation content were analyzed,the distribution of Dongsheng station and the influence of distribution were researched.The cooperation between each operation of Dongsheng station were summarized.(3)The through capacity of arrival-departure track and the arrival-departure track utilization plan for Dongsheng station were researched.Proposed the through capacity was an important indicator to measure the arrival-departure track utilization plan by summarizing the arrival-departure track.The through capacity of arrival-departure track and the influence factors for Dongsheng station were analyzed.The arrival-departure track utilization plan for Dongsheng station were researched.(4)The optimization methods of arrival-departure track utilization plan for Dongsheng station were researched.The limiting factors of arrival-departure track for Dongsheng station were researched.The optimization model of arrival-departure track utilization plan for Dongsheng station were established.The multi-objective optimization algorithm of arrival-departure track utilization plan for Dongsheng station were designed.The adaptability of Lingo software to solve the optimization problem were analyzed.(5)The profile of Baoshen railway,the surrounding road network of Baoshen railway and the general situation of Dongsheng station were analyzed.The software Lingo was used for establishing the mathematical model of optimization algorithm and solving the problem.The optimum solution of arrival-departure track utilization plan for Dongsheng station were obtained.The results showed that optimized arrival-departure track utilization plan for Dongsheng station had a high utilization ratio,and the arrival-departure track have been used in balance.
