摘　　要：[目的]研究粮食银行物流成本的数学模型。[方法]根据粮食银行物流链的模式,就单一品种(稻谷)一年内的物流成本建立了数学模型,并针对一个拥有3个供应点、3个配送点和6个销售点的小型粮食银行用LINGO软件编程求解,获得全局最优解。[结果]粮食银行的物流链模式类似于3水平分配(即有一中间环节)的转运问题。粮食银行的物流成本主要由仓储成本和运输成本构成。建立的数学模型属于线性规划,通过LINGO编程计算,得到了实例(小型粮食银行)的全局最优解,最小物流成本为4 227.51元。[结论]该研究建立的粮食银行物流成本的数学模型可寻求到最优运输方案,减少总成本。[ Objective ] The research was to study the mathematical model on logistics cost of food bank. [ Method] According to the logistics chain model of food bank, the mathematical model of logistics cost on single variety （paddy） in 1 year was established. The programming and solution of a small food bank with 3 supply sites, 3 distribution sites and 6 selling sites was solved with LINGO software, and the global optimum solution was obtained. [ Result] The logistics chain model of food bank was similar to a transshipment problem of 3 level assignments （namely it had an intermediate link）. The logistics cost was mainly composed of warehouse cost and transportation cost. The established mathematical model belonged to a linear program, the global optimum solution of the example （ small food bank） was obtained through the LINGO programming calculation, and the lowest logistics cost was 4 227.51 yuan. [ Conclusion] The mathematical model of the logistics cost of food bank that established in the study could seek for the optimum transportation scheme and decrease the total cost.
