Simulation Research on Logistical Cost Optimization of International Soybean Trade

摘要

Soybean is a bulky agricultural product whose trade liberalization was implemented earliest in China.International soybean trade develops prosperously between soybean supply countries and China in recent years.Based on the related researches,the paper tries to simulate logistical cost optimization of international soybean trade.In the paper the new mode of import soybean logistics in China that logistics center is vital node connecting with production countries and processing enterprises is studied.The constraint equation with target being the minimum of the total cost of the logistics system is established using the new mode of logistics center.At the end Tianjin Port is taken as the case for simulation solution.
