服务水平约束下的粮油库存控制策略研究

Research on inventory policy of grain and oil under restriction of service level

从保持库存的稳定性出发,分析了商品变质率、缺货成本和库存率等因素对库存成本的影响,在受服务水平约束的条件下,建立库存控制模型。在模型的基础上对变质成本与库存成本的关系进行了研究,并给出了求解最优库存和最小成本的方法。最后通过实例仿真,证明了该模型能较好地解决此类问题。

The paper analyzed the factors affecting inventory cost with deterioration rate,shortage cost and probabilities of stock on hand and so on,and established an inventory control model based on service level constraints.It researched the relationship of deterioration costs and inventory costs on the basis of the model,and gave a method in order to solve the problem of optimization inventory and minimum costs.At last the simulation illustrated with an example,the model can effectively solve the problem better.
