Method for improving high speed rail train operation right time rate by running chart robustness

Abstract

The invention discloses a method for improving the on-schedule rate of the operation of a high-speed railway train by utilizing the robustness of a working diagram in the technical field of operation dispatching and control of high-speed trains. The method adopts a technical proposal that a preset working diagram is subject to formal representation; a polynomial matrix expression form of the working diagram is given to evaluate a feature value; then the perturbation of the working diagram is defined, and the ratio of the perturbation and the total delay time is utilized to weigh the robustness of the working diagram; a Petri network is utilized to simulate the operation of the train in a section, and the deviation of the arrival and departure time of the train and diagram-specified time produced during the simulation is fed back to the perturbation calculation; the robustness of the working diagram is calculated; according to the requirement of the robustness of the preset working diagram, the arrival and departure time of the train in the working diagram is adjusted, and then the operation simulation of the train and the robustness calculation are performed; and the circulation is performed until the robustness of the working diagram achieves the preset requirement. The method provides an evidence for establishing high-efficiency railway working diagrams and assuring the safe, punctual and high-speed operation of railways.

Description

technical field [0001] The invention belongs to the technical field of high-speed train operation scheduling control, and in particular relates to a method for improving the punctuality rate of high-speed railway train operation by using the robustness of the operation diagram. Background technique [0002] With the high-speed railways being put into use, more and more attention has been paid to the compilation of operation diagrams of high-speed trains. The compilation of operation diagram is of decisive significance to make full use of the railway capacity and meet the demand of passenger dispatch. An excellent railway operation diagram can maximize the transportation effect of the railway train according to the actual driving capacity of the railway train, and ensure that the train runs according to the scheduled departure and arrival time of the operation diagram as much as possible, that is, the actual punctuality rate of the train is as high as possible. high.
