Festival and holiday multi-day train operation scheme optimization modeling method based on motor train unit intersection

Abstract

The invention discloses a multi-day train operation scheme optimization modeling method based on a motor train unit intersection. The method comprises the following steps: inputting model information; obtaining a normal train alternative set; obtaining a holiday train alternative set; obtaining a common-day motor train unit route set; obtaining a two-dimensional space-time OD passenger flow demand; obtaining a multi-day train service network in festivals and holidays; and integrated modeling is carried out on train operation scheme compilation in the whole holiday and festival periods. According to the method, in the passenger flow peak period of holidays and festivals, the date dimension is increased for the train service network and the model decision variable, so that the train operation scheme in the whole holiday and festival period is integrally compiled, and the blank about multi-day train operation scheme integrated compilation in the existing operation scheme compilation theory and method is filled up. According to the method, the problem that the existing holiday train operation scheme compilation model lacks consideration on the motor train unit route crossing is solved, and the damage to the motor train unit route crossing structure when the operation scheme is adjusted from the demand angle is overcome.

Description

technical field [0001] The invention belongs to the technical field of high-speed railway transportation organization, and in particular relates to an optimization modeling method for multi-day train running schemes on holidays and holidays based on multiple-unit intersections. Background technique [0002] With its fast, convenient and comfortable features, EMU trains make it possible for passengers to go back and forth to visit relatives and travel within a short period of time. More and more passengers choose to travel by high-speed rail during holidays. The short-term surge in travel demand has brought peak passenger flow during holidays, which is significantly different from the spatio-temporal characteristics of passenger flow on weekdays. At the same time, the total number and structure of daily passenger flow are also changing during holidays. new requirements. On the other hand, train operation is not an isolated task. It is also related to the EMU turnover plan, s...

Problems solved by technology

[0007] Third, the compilation method commonly used in practice is not adaptable to passenger flow fluctuations during holidays, resulting in low efficiency in the use of capacity and capacity resources in some line sections

In actual production, the holiday train operation plan is artificially generated mainly by adding trains and increasing the formation of trains on weekdays. This method basically keeps the schedule of train operation on weekdays fixed except for the addition of formations, which ensures the stability of the train operation plan to the greatest extent. , but at the same time, it limits the means of formulating train operation plans for holidays

In the case of significant changes in the passenger flow demand structure during holidays, the flexible adjustment from the perspective of adapting to passenger flow fluctuations is insufficient, and it is difficult to finely match the changes in holiday passenger flow demand
