An EOQ model with deteriorating items in response to a temporary sale price

In economic order quantity models, it is often assumed that the unit purcha se cost is constant. Such an assumption is usually not fulfilled in many pr actical situations. In practice, it is observed that suppliers sometimes ov er temporary price discounts to stimulate demand, boost market share or dec rease inventories of certain items. In this paper, a deteriorating inventor y model with a temporary sale price has been developed. We shall be concern ed with finding the optimal total cost saving for deteriorating items durin g the special replenishment period. Numerical examples are presented to ill ustrate the proposed model.
