传统的库存研究中都假定物品的库存费用是固定不变的．本文通过考虑库存费的变化率为库存量的函数，并在需求线性依赖于库存水平的形式下，拓展了变库存费的变质性物品的经济批量模型．然后以系统平均利润最大化为目标。讨论了在允许短缺发生且假定短缺完全拖后的情况下模型存在唯一最优解的条件．最后给出了应用实例，分析了模型主要参数的变化对最优订货策略的影响．
傳統的庫存研究中都假定物品的庫存費用是固定不變的．本文通過攷慮庫存費的變化率為庫存量的函數，併在需求線性依賴于庫存水平的形式下，拓展瞭變庫存費的變質性物品的經濟批量模型．然後以繫統平均利潤最大化為目標。討論瞭在允許短缺髮生且假定短缺完全拖後的情況下模型存在唯一最優解的條件．最後給齣瞭應用實例，分析瞭模型主要參數的變化對最優訂貨策略的影響．

Holding costs are supposed to be fixed in the traditional researches on inventory. Taking the change rate in holding costs as the function for the amount of inventory, the paper develops economic order quantity models for deteriorating items with the demand rate as a polynomial function of the retailer＇s current inventory level. Then we work out the conditions of the existence and uniqueness of the optimal solutions that could make the average profit unit time to a maximum when shortage is allowed and backlogged completely. At last, numerical examples and sensitive analysis of major parameters are presented to illustrate the developed model.
