Train detaching and attaching shunting operation plan compilation method

Abstract

The invention discloses a train detaching and attaching shunting operation plan compilation method. The method comprises the following steps: establishing an integer model of train detaching and attaching shunting operation plan compilation; designing a branch delimitation algorithm according to the railway shunting operation characteristics, and inputting initial status and compiled status of a to-be-compiled train column into an algorithm program according to a form specified by the algorithm; using the algorithm to solve the shunting operation plan compilation problem; integrating results of the algorithm into a shunting operation schedule meeting shunting operation requirements; and outputting the integrated shunting operation schedule. The method has advantages that 1, the integer planning model is used to describe a shunting operation process without the need for using empirical rules to screen shunting schemes, and the established model automatically formulates a shunting scheme, which meets the requirements, according to the requirements of an objective function; and 2, the model considers total shunting operation quantity in the shunting operation process, optimizes shunting hook quantity and shifting vehicle quantity as a whole, and minimizes the shunting operation quantity.

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
