EPQ Model for an Item Undergoes Non- Instantaneous Deterioration Receives Price Discount Permits Delay in Payments

In this paper, an EPQ model for a single product subject to exponential deterioration under productioninventory policy using permissible delay in payments is discussed. It is assumed that a single machine produces a single product over an infinite planning horizon and the production cost is considered constant. The optimal production cycle time is derived under conditions for continuous review, deterministic demand and no shortage.
