Periodic and aperiodic combined high-speed railway running chart modeling method considering stop adjustment

Abstract

The invention belongs to the field of compilation and optimization of high-speed railway train running charts, and particularly relates to a periodic and aperiodic combined high-speed railway runningchart modeling method considering stop adjustment. The method comprises the steps of taking a periodic and aperiodic combined operation scheme and station and line information as input data; establishing a target function by taking the minimum train travel time as a target, setting an interval running time constraint, a stop time constraint, an overtaking frequency constraint, a train safety interval time constraint, a starting time domain constraint, a skylight constraint and a periodicity constraint, and obtaining a periodic and aperiodic combined high-speed rail running chart optimization model under fixed stop; and on the basis of the periodic and aperiodic combined high-speed rail running chart optimization model under the fixed stop, obtaining a periodic and aperiodic combined high-speed rail train running chart optimization model considering stop adjustment. The passenger transport service quality is improved, the passenger transport market competition is improved, and thereforethe purposes of improving a busy trunk line improving capacity and improving the passenger transport efficiency are achieved.

Description

technical field [0001] The invention belongs to the field of compilation and optimization of high-speed railway train operation diagrams, and in particular relates to a modeling method for high-speed railway operation diagrams combining periodic and non-periodical considerations of stop adjustments. Background technique [0002] In the prior art, a lot of research has been done on the compilation and optimization of train diagrams for high-speed railways. In terms of diagram optimization, foreign trains mostly use periodic train diagrams, and domestic trains mostly use non-periodic train diagrams. In the prior art, there are few theoretical studies on the combination of periodic and aperiodic operation diagrams. Most of them use the plug-in technology of periodic diagrams to realize the combination of periodic and aperiodic. In practice, manual adjustment is usually used to optimize the operation diagram based on experience. [0003] Periodic operation chart has the characte...

Problems solved by technology

[0004] 1) There is a lack of systematic combing research. Generally, the research on the "periodic + non-periodic" train diagram is mostly focused on the problem of drawing and adding lines to the periodic train diagram. "or destroy the "periodicity" of periodic trains; seldom comprehensively consider the one-time optimization method of periodic lines and aperiodic lines, and there is no systematic combing method for combining periodic and aperiodic train operation diagrams;

[0005] 2) The capacity planning of the operation diagram is not good enough

In the process of compiling the operation diagram, some capacity bottleneck sections are likely to have limited capacity, which makes it impossible to plan all the trains in the train operation plan, resulting in no solution for the model
