摘　　要：研究了有限时域下采购商面对价格上升时的订货策略问题。在分析问题的基础上提出一种新的最优采购策略,并分析了价格上升幅度对订货量的影响,以经典EOQ模型的总成本为基准,比较了本文提出的策略与文献已有策略在成本节约上的差异。本文对库存总成本的计算方法更加精确;分析表明在有限时域背景下采购商的临时订货量决定于价格上涨的幅度、在库库存以及时段长度。This paper analyzes the optimal replenishment policy, when a buyer faces imminent price in- crease under finite horizon. The paper proposes a new method to determine optimal temporary order quantity and analyzes the influences of variable prices on order behavior. Taking the total cost of basic EOQ model as the benchmark, the difference of cost savings between the proposed policy and the other policy in former literature is discussed. The calculation of total inventory cost is more accurate in the paper. The result shows order policy is determined by the increasing extent of price, on-hand inventory and the time horizon.
