Study On Logistics Distribution Network Based On Technology Of Network Opmization

Logistics as the "the third spring of gain" is more and more important in the national economy. It is propitious to develop economy, to enhance the military affairs, improve the substance and culture life of people and expand the intercommunication of technology and culture. It is practical to construct a model of logistics distribution network. The model doesn't only adapt to logistics distribution network but also adapt to other network, for example the water network and electricity network. The study on the model is so applied.In this article, we construct a model of logistics distribution network with limitation of capacity, and the capacity can be extended with cost in the limited time. We want get the lowest cost when satisfy the needed capacity of the logistics distribution network. We solve the question by using auxiliary network, and turn this problem into minimum cost flow problem. Thinking of the characteristic of the logistics transportation and distribution network, we can predigest the method of minimum cost flow problem.From the model, we can know how to arrange the transport scheme to get the lowest final cost (the transport cost adds the expand cost) when the capacity of the logistics transportation and distribution network is extended with cost in the limited time.
