Problems solved by technology

Therefore, the existing train operation plan diagram modeling method does not consider the overtravel between trains with different origins and destinations, and the calculation of the full travel time of the train under the road network condition is still not accurate enough

Embodiment 1

[0077] The present invention provides a modeling method for a high-speed railway networked train operation plan diagram, such as figure 1 shown, including:

[0078] Step 01: Select the high-speed railway network, including: all nodes and connecting lines on the train operation plan diagram;

[0079] Step 02: Construct decision variables and logical relationships of different train route nodes;

[0080] Step 03: According to the decision variable and logical relationship, construct the calculation formula of the whole train travel time;

[0081] Step 04: Construct preset constraints and objective functions related to the train operation plan diagram;

[0082] Step 05: Based on steps 03-04, build a train operation scheme diagram model, compile and solve the operation scheme diagram model based on the target software, and obtain a scheme diagram to be verified.

[0083] For the above steps 1-5, see the specific execution steps figure 2 .

[0084] In this embodiment, firstly...

Embodiment 2

[0087] On the basis of embodiment 1, select the high-speed railway network, including: in the process of all nodes and connecting lines on the train operation plan diagram, also include:

[0088] Define the node, and denote by s, and the set of the nodes is S, s∈S;

[0089] Define the line connection relationship between adjacent nodes of two different stations as interval e, namely Indicates slave node s k to node s k' The formed interval, including direction, the interval set is E;

[0090] Wherein, the node is the throat area of ​​the station in the train operation plan diagram.

[0091] The beneficial effect of the above technical solution is: by determining the nodes and connecting lines, it is convenient to ensure the validity of obtaining basic information and provide a data basis for subsequent model building.

Embodiment 3

[0093] On the basis of any one of embodiments 1-2, in the process of constructing decision variables and logical relations of different train route nodes, it also includes:

[0094] Select the train l on the train operation plan diagram, the train set is L, l∈L;

[0095] Define the time when train l passes through node s as is a decision variable;

[0096] Define the i-th train l i with the jth train l j The context of the node s in the common path is For the decision variable, construct the description and The calculation formula of the logical relationship is as follows:

[0097]

[0098]

[0099] in, as the decision variable means train l i , train l j The moment of passing through node s, in minutes; Is the decision variable, the value is 0 or 1, when the train l i ahead of the train l j When passing through node s or two trains passing through node s at the same time, It is equal to 1, otherwise it is equal to 0; M is a known parameter and is a...

Abstract

The invention provides a modeling method for a high-speed railway networked train operation scheme diagram, which comprises the following steps: step 01, selecting a high-speed railway road network which comprises all nodes and connecting lines on the train operation scheme diagram; 02, constructing decision variables and logic relations of different train path nodes; step 03, according to the decision variables and the logic relationship, constructing a calculation formula of the whole travel time of the train; step 04, constructing a preset constraint and a target function related to the train operation scheme diagram; and 05, based on the steps 03-04, constructing a train operation scheme diagram model, and compiling and solving the operation scheme diagram model based on the target software to obtain a to-be-verified scheme diagram. All overrun of different trains in the same interval can be accurately identified, the accuracy of a compilation result of a networked train operation scheme diagram is improved, and the difficulty of compiling a detailed diagram by a railway department is reduced.

Description

technical field [0001] The invention relates to the technical field of transportation, in particular to a modeling method for a high-speed railway networked train operation plan diagram. Background technique [0002] At present, my country's high-speed railway operation mileage has ranked first in the world, and it is changing from a period of rapid construction to a period of efficient operation. The huge railway network and diversified travel needs of passengers have brought unprecedented challenges to the preparation of my country's high-speed railway transportation organization plan. Compilation of passenger train operation diagrams, also often referred to as passenger train timetable compilation, usually includes two steps. , running route and specific stop) as input, determine the departure and arrival time of the train at the departure station, final arrival station, railway bureau boundary station and main stop station, and clarify the basic frame structure and over...
