| 摘 要： | 研究了两种可替代物品的经济订货批量问题.在计划期内,若某一种物品发生缺货,则可以被另一种物品以一定的替代率代替补充,以库存系统的总费用最小为目标函数,证明了最优策略存在的唯一性,并给出了求解最优订购策略的算法,最后通过两个算例验证了算法的最优性.

| Abstract: | The paper considers the economic order quantity problem with two substituting items, in which shortage of one item may be replenished by the other item with the fixed substituting rate in planned horizon. In order to minimize the total cost, we prove the existence and uniqueness of the optimal policy and present an algorithm to find the optimal ordering policy, at last we show the model and solution procedure by two examples. |
