Study On The Method Of Periodic Diagram Generation For High-Speed Railway

The periodic train operation diagram, as an advanced train operation diagram mod e, has been put into use widely abroad, and some high-speed railways have been cond itionally qualified for the periodic train operation diagram, whose diagramming theoretic al study at home has just initialized, in reference to the existed study fruits of periodic and non-periodic train operation diagram, this paper analyzes the conditions, characters, modals and algorithms of the periodic train operation diagram of the passenger-dedicat ed lines.Firstly, based on the circumstances of periodic train operation diagram all over the world, the paper promotes the advantages of periodic operation for trains, and in term s of the conditions and updates at home, the paper analyzes the applicability and feasi bility of periodic operation diagram for passenger-dedicated lines.Secondly, the paper make an analysis on the programming and key issues, which include the generation of the periodical operation scheme, the handle of periodic train table issues, the initial point distribution methods, as well as other aspects of conflict resolution issues.Thirdly, after the conception and nature of the periodic event planning theory intr oduction, the advantages and shortcoming comparison of two different train operation d iagramming methods, targeting at minimizing the shortest passenger travel time, with th e periodic train operation time, train stop time, the train starting fluency, the safety int erval time, train interval time of different directions as the constraints, the paper builds bilateral periodic train operation modal with parameters.At last, in terms of the periodic train operation diagram features, the paper will s olve all the problems with the Benders algorithm, to be specific, based on its basic pri nciple and methods, and the paper design a railway section with8stations within one hour, during which nine high-speed trains are running, the paper makes out the arriva1and departure time, the periodic train operation diagram, as well as an analysis on t he operation diagram structures.
