Abstract: Inflation plays a very interesting and significant role: it increases the cost of goods. To safeguard from the rising prices, during the inflation regime, the organisation prefers to keep a higher inventory, thereby increasing the aggregate demand. This additional inventory needs additional storage space that is facilitated by a rented warehouse. Ignoring the effects of time value of money and inflation might yield misleading results. In the present study, a |two-warehouse inventory model with linear trend in demand under the inflationary conditions| has been developed. A rented warehouse (RW) is used to store the excess units over the capacity of the own warehouse (OW). The stock is being transferred from rented warehouse to own warehouse in a continuous release pattern with per unit transportation cost being factored in. The solution methodology provided in the model helps to decide on the feasibility of renting a warehouse. The results have been elucidated with numerical examples.
