| Abstract: | In this paper,we develop an inventory model for finding the replenishment schedule for an inventory system,in which items deteriorate at a constant rate and demand is price-sensitive when the supplier gives quantity discounts.It is shown that when the supplier gives quantity discounts,the buyer's demand increa-(ses).Sensitivity analysis with the numerical example shows that order quantity and replenishment cycle are very sensitive to the deterioration rate,but the retailer's profit per unit time is not.The retailer's unit selling price and profit per unit time are very sensitive to the price-sensitive parameter.A numerical example is presented. |
