Research On The Organization Of Direct Wagon Flow In Heavy-Haul Loading Area

With the rapid development of the society and economy of our country, the consumption of energy which is the primary factor is gradually growing. However, because of the unbalance of economical development and coal exploration, together with the relative backward of our railway system, the ability of railway is in shortage of supply. In order to meet the demand of goods transportation more effectively, the railway system should promote the organization of wagon flow and CDB way of trains. For the heavy haul railway, which has the stable source of bulk cargo, direct transport from loading area is a significant way to accelerate the turnover of goods and reduce the cost of transport. It is a efficient way to relieve the stress of railway system.The main idea of this article is to discuss the organization of wagon flow in heavy-haul loading area. With the analysis of the developing trend and organizing method of heavy-haul transportation domestic and abroad, together with the theory of direct transport wagon flow of loading area, this article makes an study on how to organize the direct transport for wagon flow. The contents of the thesis include the following several aspects mainly:Firstly, this article analyzes the standard of the cost of wagon flow in the loading area and uninstalling area. Then, according to the varieties of organization of wagon flow in loading area, this article set a0-1nonlinear programming model. The goal of this model is to search for a optimized way to organize the wagon flow by the least cost, within the limit of uniqueness of wagon flow organization and the ability of technical station on the route of railway. At the end, this article extracts the statistic of wagon flow and technical station in loading area from the heavy-haul railway, and sets it as an example for the model mentioned upside, and using genetic algorithm by the MATLAB language to solve the model. In addition, the theory of organization for wagon flow in the loading area is an expand of previous. It is of significance ideal and practical to some extent and provides a method to solve problems like this.
