A train operation plan generation method considering the needs of enterprises

Abstract

The invention provides a method for generating a train operation plan considering the needs of enterprises. The method includes: establishing a space-time network corresponding to the road network structure; based on the space-time network corresponding to the road network structure, taking the minimum sum of the train transit time as the objective function, taking the departure station of the truck, the arrival station of the truck, the intermediate node station, Using capacity and intermediate node capacity as constraint conditions, establish a train operation plan optimization model considering the needs of enterprises; use mathematical programming algorithms to solve the train operation plan optimization model, and determine the train operation plan according to the solution results. The method of the present invention considers the unloading capacity of the arrival station, and at the same time, considers the classification of the goods of the arriving freight trains, so as to ensure the arrival of different types of goods in proportion, avoid irregular or concentrated arrival of freight trains, reduce the turnaround time at the bottom of the car, and reduce the raw materials of enterprises Reduce inventory costs and improve the quality of railway transportation services.

Description

A method of generating train operation plan considering the needs of enterprises technical field The present invention relates to the technical field of railway dispatch and command, in particular to a kind of train operation plan considering enterprise demand Generate method. Background technique [0002] Driven by the policy of "return to railway", railway freight has increased significantly, and at the same time, it has also put forward higher requirements for the turnover of railway freight cars. Require. Under the existing infrastructure and technical conditions, the dwell time of trucks before entering the line has become the main factor affecting the vehicle turnaround time. factors, the backlog of traffic at the arrival end needs to be solved urgently. At the same time, the irregular arrival of trains also brings higher inventory costs to enterprises. Book. The train operation plan can indicate the operation of the train in the section and the arrival time, ...

AI Technical Summary

Problems solved by technology

However, the existing studies only consider the demand for the total number of arriving trains within a certain period of time, and lack the refinement of the optimal arrival time of each train and the corresponding operation process of each train, and there is no detailed analysis for trains of different types of goods. To make a distinction, the granularity is relatively large, which cannot meet the actual production needs of the enterprise
