Research On The Theory And Technology Of Market Orientation Dynamic Freight Train Diagram

With the continuous development of China’s railway network,China’s railway has entered a new era of "dual-network integration" of general speed and high speed,which leads the world’s railway development,and the tension of railway transportation capacity has been effectively relieved.At the same time,with the rapid development of social economy,the requirements for the diversification,high quality and timeliness of railway freight transportation services are constantly increasing.However,as the theory and technology of railway transportation organization in China fail to achieve innovation and breakthrough,the railway still can’t carry out the whole chain transportation organization innovation design according to the market change,and can’t meet the dynamic change demand of the transportation market.Based on this,Based on this,this paper studies the theory and technology of market orientation dynamic train diagram,establishes a new mechanism of planning railway transportation organization that comprehensively,rapidly and accurately responds to the dynamic market changes,realizes dynamic railway transportation planning and precise dispatching command according to the market changes and the requirements of arrival time limit,and fundamentally improves the adaptability of railway to the dynamic market changes ability,the main contents are as follows:This paper analyzes the domestic and foreign railway freight transportation organization mode,and summarizes the shortcomings of China’s railway freight transportation organization mode.Based on this,this paper studies the market orientation dynamic planning railway freight transportation organization method,and constructs the railway transportation organization innovation theory with the market orientation dynamic train diagram as the core.Based on the analysis of the existing problems of the establishment and management mechanism of train diagram at present in China,the market orientation dynamic train diagram establishment and management mechanism is constructed,and the functional setting and organization setting scheme of the train diagram establishment and management center of the whole railway are put forward.Investigating the mechanism of market orientation dynamic freight train diagram establishment,including the connotation,principle,content and process.Then,based on the dynamic freight train operation plan,considering the requirements of the train’s connecting time in the station and the limitation of the arrival time,the dynamic freight train operation line selection model is established with the goal of the minimum travel time consumption in the train operation process,and the simulated annealing algorithm is designed to solve the model.Based on the analysis of the market orientation dynamic freight train diagram system requirements,the system objectives are determined,and the overall architecture,architecture and functional structure of the system are investigated.
