As a matter of fact, the capacity of any warehouse is limited, so a firm has to hire a warehouse called rented warehouse (RW) for storing the excess units over the fixed capacity W (say) of the own warehouse (OW). Practically the RW is assumed to offer better storing facilities than the OW, which results in a lower rate of deterioration and is supposed to charge higher holding cost than the OW....

In this research work, a wholesaler-retailer-customer supply chain model for a deteriorating item is considered, where the retailer's warehouse in the market place has a limited capacity. The retailer can rent an additional warehouse (rented warehouse) if needed, with a higher rent compared to the existing warehouse (own warehouse). The customers' demand of the item is linearly influenced by th...
