Abstract: In this paper, an order level inventory model is discussed with the demand rate that is a continuous quadratic function of time. It is assumed that a constant fraction of the inventory deteriorates per unit time and shortages in inventory are allowed and completely backlogged. The effect of inflation and time value of money are taken into account, considering both internal and external inflation rates. A numerical example is shown to illustrate the model and sensitivity analysis of the optimal solution with respect to the parameters of the system is carried out.

Keywords: inventory modelling; shortages deterioration; time quadratic demand; inflation; economic order quantity; EOQ; replenishment policy; SFI policy.
