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...

[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 system
