| Abstract: | In this paper, an inventory model for deterioration items with ramp type demand rate and Shortage partial backlogging is built. The inventory management problem of deterioration items with Weibull distribution under exponentially ramp type demand is investigated. The total inventory cost functions of two cases per unit of time under the shortageconditions are analyzed and an optimal replenishment policy of deterioration items is derived. Finally, numerical examples also indicate the inventory model meet practical situation. |
