Economic Analysis on Transportation Delaminating in Distribution System

The operation of distribution system and the process of transportation operations are tied up closely. The character of transport flow in distribution system influences the economic benefit directly. By technical & economic analyzing of the distribution operation, this paper gives a detailed theoretic analyzing on the relationship between the characteristics of transportation cost and the hierarchy of distribution network, as well as on the levels and forfication under minimum transport cost, etc. By means of determining the mature and quantities of distribution, assemblage and transfer layers in distribution system, the conclusion is made that in perfect situation, the optimal distributing construction depends on distance and density of requirement, and then, the method to define distribution framework and optimal hierarchy according to economic scale in practice is put forward.
