存货是企业生产与运营的核心成本,存货过多或不足都会使企业增加不必要的费用和损失。存货控制的目的就是使存货的总成本即取得成本,储存成本,缺货成本三者之和最低。在批量采购的情况下,采购数量的多少与价格折扣有直接的关系,运用数学模型来说明如何在该情况下进行存货控制,使存货控制模式更接近现实具有重要意义。 Inventory is the core cost of the company’s production and operations. Excessive or insufficient inventory will increase the company’s unnecessary costs and losses. The purpose of inventory control is to make the total cost of inventory, ie, acquisition cost, storage cost, and out-of-stock cost, be the lowest. In the case of bulk purchases, there is a direct relationship between the number of purchases and price discounts. Using mathematical models to illustrate how to control inventory in this case makes it more important to have an inventory control model that is closer to reality.
