Study On The Transportation Network Optimization Of Import Bulk Grain

With the lasting and appropriate development of national economy and increase of population, the demands of grain in China have shown a significant rising trend. Meanwhile, there is a certain level of sales gap on China's grain production. China has to rely on international grain market by means of importing bulk grain to solve the problem of insufficient domestic supply. To guarantee the future grain consuming and national strategic reserving, it is meaningful and worthwhile to establish a reliable imported bulk grain network.Based on the methods of qualitative and quota, through studies on the domestic and foreign literature and investigation on the related enterprise massively, the present Paper conducts the deep research to the above question with methods of logistics system. Firstly, this study reviews on the literatures of transportation network for imported bulk grain. Secondly, this study introduce China's exists bulk grain production and marketing gap. China has to rely on international grain market by means of importing bulk grain to solve the problem of insufficient domestic supply. Analysis of China's import bulk grain transportation network system, three layers of node constitute of China's imports of bulk grain transportation network. Take the theory of scientific logistics and the massive collection correlation data as the foundation, the paper has established the model of the smallest cost of the entire network transportation system. The model is carried out by the software of GAMS. The aim of this paper is that it can provide some theoretical reference instruction and valuable policy making basis on the bulk grain transportation for the policy-maker in our country.
