Passenger train operation scheme diagram drawing method

Abstract

A passenger train operation scheme diagram drawing method disclosed by the present invention comprises the steps of constructing a railway road network topological structure diagram, establishing a road network topological structure diagram based on stations; according to the road network topological structure diagram, utilizing a fuzzy set to describe a target function convenient for passengers to travel, and establishing a road network passenger train operation scheme diagram drawing and optimization model by taking the station and path capability as the constraint; utilizing a rough-fuzzy soft set theory to describe the important degrees of the road network stations, and transforming the road network passenger train operation scheme diagram drawing and optimization model into a passenger train operation scheme diagram drawing model which is drawn according to the important degrees of the stations; according to an ant colony algorithm based on the station and path capability cooperation, solving the passenger train operation scheme diagram drawing model which is drawn according to the important degrees of the stations rapidly to obtain a passenger train operation scheme diagram. By the technical scheme of the present invention, the implementation possibility of the passenger train operation scheme diagram is conducive to being improved.

Description

technical field [0001] The invention belongs to the technical field of train route planning, and in particular relates to a method for compiling a passenger train operation plan diagram. Background technique [0002] The train operation diagram stipulates the sequence of various trains occupying sections, the arrival, departure or passing time of trains at each station, the running time of trains in each section, the standard of stop time of trains at stations, and locomotive crossings, etc. It connects the transportation and production activities of the entire road network into a unified whole. The train diagram is the comprehensive plan of railway transportation work, the basis of railway traffic organization, and a tool for coordinating various railway departments and units to carry out production activities according to certain procedures. The focus of the preparation of the train diagram is to solve the overall layout of the train diagram. It is the skeleton and core of...

Problems solved by technology

[0006] 1. In the prior art, no matter whether it is a general-speed railway train operation scheme diagram or a high-speed railway train operation scheme diagram, the preparation is mainly under unconstrained conditions, with the two goals of passenger convenience or enterprise economy, without considering stations, There is a large gap between line capacity constraints and actual application requirements, making it difficult to provide effective support for the compilation of train diagrams

[0007] 2. The scope of the preparation of the train operation plan diagram in the existing technical scheme is concentrated in a certain operation section, and there are also a few cases where the normal speed road network and the high speed road network are considered alone, and there is no connection between the high speed railway and the normal speed railway to form a network Happening

[0008] To sum up, the existing technology does not take into account the situation that high-speed railways and ordinary-speed railways are connected to form a network, and large passenger stations need to run a large number of trains due to political and economic reasons, resulting in a relatively tight equipment capacity of passenger stations, especially the arrival and departure capacity. In this way, it is easy to cause the passenger train operation plan diagram to be unrealizable
