A method for preparing a shunting operation plan for detachment and suspension trains

Abstract

The invention discloses a method for preparing the shunting operation plan of the detachable train, which comprises the following steps: establishing an integer model for the preparation of the shunting operation plan of the detachable train; input into the algorithm program according to the form specified by the algorithm; use the algorithm to solve the shunting operation planning problem; integrate the results of the algorithm into a shunting operation schedule that meets the shunting operation requirements; and Output the integrated shunting operation schedule. The present invention has the advantages of: 1. The integer programming model is used to describe the shunting operation process, and there is no need to use empirical rules to screen the shunting scheme, and the established model can automatically formulate a shunting scheme that meets the requirements according to the requirements of the objective function . 2. The model considers the total amount of shunting work in the shunting operation process, and optimizes the number of shunting couplers and the number of shunting vehicles as a whole to minimize the amount of shunting work.

Description

technical field [0001] The invention relates to the technical field of train dispatching, in particular to a method for preparing a shunting operation plan for detached and attached trains. Background technique [0002] Railway shunting operation is an important part of the railway transportation process. In the technical station, the traffic flow of the detached trains is assembled according to the direction, and the sequence of the trains to be assembled in the lane is random, which does not meet the requirements of the train formation plan. The purpose of the shunting operation of marshalling and detachment trains is to transform the random arrangement sequence of detachment and detachment trains into a train group arrangement sequence that meets the requirements of the train marshalling plan. [0003] Traditional railway shunting operations mainly contain the following prior art. [0004] Existing technology 1: Coordinating and matching method Through the steps of "dro...

AI Technical Summary

Problems solved by technology

[0010] 1. When the original number of trains to be assembled is not an integer power of 2, there will be more candidate shunting schemes, and the overall planning counterpart method does not clearly stipulate how to effectively select the shunting scheme for marshalling

[0011] 2. The shunting plan obtained by the matching method has too many hooks

[0012] 3. When the number of shunting lines is limited, the overall planning counterpart method does not give a specific solution method

[0016] 1. It is not comprehensive enough to use the converted hook number as the evaluation index

[0017] 2. When the number of shunting lines is limited, the overall coordination method will no longer apply

[0027] 2. When the number of shunting lines is limited, the method based on the binary tree will no longer be applicable

Preparing detached trains according to station order is the most complicated task in the preparation of many shunting operation plans
