Embodiment Construction

[0080] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0081] The present invention proposes a method for optimizing a station stop scheme of a high-speed railway train, in order to deeply excavate the attribute characteristics of a station, and propose a new model to realize an optimized stop plan. In the first stage, the stations are classified using an unsupervised cluster analysis method. In the second stage, a modified Markov decision process (MDP) is used to optimize the stop scheme of the high-speed railway. technical framework such as figure 1 shown.

[0082] The first stage: a method for classifying stations based on station node attribute characteristics

[0083] In this stage, by inputting the characteristic variables of the station, cluster analysis is used to dynamically divide the station l...

Abstract

The invention discloses a high-speed railway train stop scheme optimization method. The method comprises the steps: step 1, dividing station grades based on station node attribute characteristics; step 2, establishing a train stop scheme model based on a Markov decision process, including (1) setting a model structure; (2) a decision set; (3) state and state filtering; (4) benefit value definition; (5) transition probability; and (6) establishing a stop scheme optimization model based on the improved Markov process. The method has the advantage that the train transportation capacity of each section is utilized more effectively. The wasted train transport capacity and excessive congestion can be reduced. The passenger carrying rate of passengers can be improved by reducing the wasted traincapacity; congestion is reduced, and comfort can be improved.

Description

technical field [0001] The invention relates to the technical field of train operation management, in particular to a method for optimizing a station stop scheme of a high-speed railway train based on station node attribute characteristics. Background technique [0002] High-speed railway has the advantages of reliability, safety, low emission and energy saving, and it is of great significance in daily life. With the increase in passenger demand and the ever-increasing size of the high-speed rail network, transport organization is becoming more and more complex. However, train operation management must be maintained at an acceptable level of efficiency. The train stop plan is a key element in the high-speed railway operation plan, which needs to reduce the operating cost of the railway company as much as possible while meeting the ever-increasing passenger demand. The stop plan directly affects the service level of each station and the passenger load factor of the train, a...
