Research On Key Technology Of High-Speed Railway Train Operation Plan

The high-speed railway of our country has gradually formed into a network, with the characteristics of high speed, high density, and extensive range. As the high-speed railway of our country has great difference with high-speed railway abroad and existing railway inland in management model, targeted speed, equipments, etc. Draw on the operation experience of foreign high-speed railway and existing railways can not completely solve the problems in high-speed railway the operation and management. High-speed railway passenger train operating scheme and train diagram are important daily plans that railway department to carry out, besides they are the key technology of high-speed railway train operation plan. Therefore, study the establishment method of high-speed railway passenger train operating scheme, train diagram has great significance to improve the level of operation of high-speed railways in our country.Firstly, this paper combined with the actual situation of Beijing-Tianjin high-speed railway and Beijing-Shanghai high-speed railway, then summarize the characteristics of passenger train operating scheme and train diagram by statistical data.Secondly, it analyse the factors of the passenger train operating scheme, and discussed train running section,train number calculate method. On this basis, emphasize studied the stop schedule plan optimization method, built a multi-objective0-1integer programming model stop schedule plan that based stop rate, designed heuristic search algorithms based on stochastic optimization, verify the feasibility of the model and algorithm, obtained satisfactory results.At last, from train diagram establishment objectives, principles, elements and other aspects perspective, it studied the differences between the high-speed railways train diagram and existing railway train diagram. On this basis, summed up the high-speed railway train diagram establishment difficult points. Detailed studied establishment of the peak hour train diagram and over-line train running lines, and proposed relevant establishment method from the train diagram structure arrangements, establishment order, stop and overtaking, according to their different features.
