Research On Analysis Of Railway Freight Transportation Assembly Mode Based On Differential Cost

With the accelerated development of the economy of our nation in recent ten years, the continuous progress of society and the striking change of science and technology, the demand about transportation is gradual increasing. Consequently, railway interests should keep abreast of the times and grant people’s ever-changing requirements about the quantity and the quality of railway transportation. It has completed the transformation from the planned economic system to the market economic system in our country in recent20years. Therefore, railway enterprises are not only the production units, but also implement the planned and regulatory producing activities based on market demand.The planning organization system is more suitable for the economy market and the society information demands, it has strongly development potential than the tissue type organization system, which our country is using now. This assembly mode refers to the mode which based on train timetable. This mode can greatly enhance the timeliness of goods railway transportation; improve the competitiveness of railway transportation; make the organization more responsive to the development needs of modern society.The paper studies the whole designated rally of the marshalling station train rally mode in more depth under the background of the subject which is managed by the tutor. First of all, the paper analyzed about the complete table point assembly mode in the terms of theory. It expounds that the necessity and feasibility of the complete table point assembly mode from society, technology, economy and so on, and the influence on the operations of the marshalling station. In the second place, it adopts the genetic algorithm to tackle the complete table point assembly period model based on the departure frequency. Furthermore, calculate the rally plan indicators of different frequency through build up the complete table point assembly arithmetic system. At last, according to differential cost, compare the complete table point assembly mode, the allocation assembly mode and the relaxation of table point assembly mode, then obtain the corresponding conclusion.
