AN EOQ MODEL WITH STOCK-DEPENDENT DEMAND, SHORTAGE, INFLATION AND TIME DISCOUNTING

This paper develops a finite time-horizon deterministic economic order quantity (EOQ) inventory model with shortages, where the demand rate at any instant depends on the on-hand inventory (stock level) at that instant. The effects of inflation and the time value of money are take n into account, considering two separate inflation rates: namely, the internal (company) inflation rate and the external (general economy) i nflation rate. The results are discussed with a numerical example and particular case of the model is discussed in brief. A sensitivity anal ysis of the optimal solution with respect to the parameters of the sys tem is carried out.
