A Study On The Routing Scheduling Optimization Of District Stations

The speed of the building railway modernization and information was so fast.compared with other way of the transport,Rail transport has obvious advantages.And the railway transportation has a very important role in social development.However,As the basic unit of the whole process,the railway stations concenteated on the most of the technical equipment.Actually,the level of the automation and intelligence should be improved.The problem of the railway district stations route scheduling.It provides an important theoretical foundation for improve the working efficiency of the district stations and come true the automatic route scheduling of the district stations.At the same time,It can reduce the extent of the human intervention.It has practical significance to achieve district automatic operation.This article will start from the actual situation of our country.Based on the research of the former people.Adopted the methods of the mathematical modeling to study and analysis the question of the railway district stations route scheduling.The paper is as mainly as follows:(1)Technical working analysis of the railway district stations.In this part.Introduce the classification of the railway district stations and introduce the district stations figure and related equipment.Analysis the content of the technology operation and process for railway district.In particular,it analysis the train and shunting locomotive operations.(2)Construct the railway district station network model.By describing the node,the paper constructs the railway district station network model.According to the actual production process of the railway,it describes the properties of the line.According to the device properties to design the Route Search Algorithm.And finally,use the mathematical language to describe the process of the Route Search Algorithm.(3)Construct multi-objective programming model of the district stations route scheduling.As the basic of the district station network,analytic the use of the route.And consider the conditions of the select preferences.The optimization objectives are maximum preference trains selecting routes,balanced utilization of tracks.And consider the constrains of the dispatching and receiving trains.Then construct multi-objective programming model of the district stations route scheduling.(4)Genetic algorithm is used to settle the route assignment problem.Taking into account the complexity of the route scheduling.In the algorithm design,Using tournament selection strategy for each sub-target in order to dimensionless processing.To ensure the optimum individual can be genetic.(5)Take Jinchang as an example for analysis,And established a network structure of the two Jinchang station throat area.Using the C++ programming to achieve genetic algorithm.then get the Jinchang station route scheduling scheme.And analysis this scheme,it prove the correctness and effectiveness of the route scheduling model and algorithm...
