Embodiment
[0118] Taking China-Europe trains as an example, select good sources of goods from the cities where China-Europe trains operate, and take Xi'an as a hub source of goods, such as image 3 shown;
[0119] The above selection process is based on the following reasons: First, it can make full use of the existing sources of goods to ensure the normal operation of trains, and it is convenient to test the effect of the radiation range of the hub nodes of the land bridge passage; The intersection, the development potential city in the central and western regions), is convenient for further planning the development of the hub node and the expansion of the transportation network; third, the container flow along the way can be used as a supplement (as one of the hub gathering centers of the China-Europe freight train, it has the effect of agglomeration of supply sources) , On the premise of maintaining the speed of delivery, enhance accessibility, reduce the assembly time of container flo...

The invention relates to a land bridge channel hub node radiation range division method based on an oil spill model. All lines of a logistics channel compete with one another, the line overlap ratio is high, the transportation cost is difficult to control, and the logistics cost of cargo transportation is further increased. The method comprises the following steps: selecting a plurality of city goods sources, taking one city goods source as a hub goods source, and taking the rest city goods sources as other goods sources; calculating attraction values of the hub goods source and other goods sources by adopting an entropy method; and calculating the attraction area of the hub goods source based on the oil spill model so as to determine the radiation range of the hub goods source. By means of the method, the radiation range of the land bridge channel hub node can be determined, goods picking of a logistics channel within the reasonable radiation range is facilitated, on the premise that the delivery speed is kept, the accessibility is enhanced, the train running frequency is improved, the service quality is guaranteed, goods sources are further attracted, and the service life of the logistics channel is prolonged. Therefore, the logistics transportation cost is reduced, and the market competitiveness is improved.
Description
technical field [0001] The invention relates to the field of railway cargo transportation, in particular to a method for dividing the radiation range of a land bridge passage hub node based on an oil spill model. Background technique [0002] The measurement of the radiation range of the logistics hub is the premise and basis for effectively counting the service volume of the logistics hub and scientifically planning and designing the logistics hub. The radiation range of a hub refers to a relatively stable area that a hub city can radiate. For example, when the cargo in a certain area is transported, when the owner prefers to choose the railway station of the hub city for transportation, then this area is the radiation range of the hub. For example, the currently constructed China-Europe freight train to Europe plays an important role in promoting trade cooperation and infrastructure construction among countries. image 3 , which has three passages: west, middle and east. ...
