Method for flexibly scheduling passenger trains in high-speed rail network under random demand conditions

Abstract

The invention relates to a method for flexibly scheduling passenger trains in a high-speed rail network under random demand conditions. The method is built on the basis of optimizing a daily road section passenger capacity supply model, takes random variation conditions of passenger flow, limitation of quantity of motor train units put in the high-speed rail network, seating capacity of trains, passenger stranding conditions in stations and the like into consideration and takes the passenger capacity of road sections put into use as a decision variable and the quantity of passengers as a random variable to build a model for flexibly scheduling the passenger trains in the high-speed rail network under the random demand conditions. A flexible passenger train scheduling scheme meeting different passenger demands is obtained by solving the model, thus providing a theoretical reference for a decision maker to schedulethe passenger trains in the high-speed rail network.

Description

technical field [0001] The invention relates to a method for flexible scheduling of passenger trains in a high-speed railway network under random demand conditions. Background technique [0002] The train operation in the high-speed rail network has the requirements of high speed, high density, high punctuality rate and high safety. Since Japan built the world's first high-speed rail, the Tokaido Shinkansen, in 1964 and put it into operation successfully, high-speed rail has grown rapidly around the world due to its high-efficiency economic and social benefits. my country's high-speed rail is also in a stage of rapid growth. According to the requirements of my country's "Medium and Long-term Railway Network Planning", by 2020, more than 16,000 kilometers of high-speed lines will be built to form the basic framework of my country's high-speed rail network to solve the transportation of my country's main railways. capacity tension. [0003] For high-speed rail network operato...

AI Technical Summary

Problems solved by technology

However, at present, the preparation of train operation plans in my country's high-speed rail network mainly depends on the fixed passenger flow, and the daily passenger capacity is fixed.

In the actual scheduling work, although the change of passenger flow has a certain pattern in a large range, this pattern is not necessarily reliable in certain periods of time, and there must be a large difference between the change of passenger flow and the required transport capacity

The traditional traffic dispatching method ignores the random fluctuation of passenger flow in each time period during the actual operation process. In the case of high-speed and high-density traffic, such a dispatching scheme cannot fully meet the passenger's travel needs.
