Abstract

Inventory control of products with finite lifetime is quite relevant with many business organizations. Since deteriorating items require special storage facilities, the retailer may have a small warehouse providing such facilities and so the need for an additional rented warehouse may arise. In this paper we have considered two warehouses (own warehouse $(OW)$ and rented warehouse $(RW)$) inventory model with ramp type demand, replenishment rate is infinite, shortages are not allowed and different levels of item deterioration in both warehouses. The goal of the study is to find the optimal replenishment policies for minimizing the total inventory costs and to prevent the deterioration of items. An algorithm is developed to find the optimal solution. Finally, numerical examples are provided to illustrate the proposed model.
