Ordering Policies of Deteriorating Items Under Permissible Delay in Payments
研究了供应商允许延迟付款时，易变质品的最优订购量如何确定，并给出了数值算例，对库存管理者有参考价值。
In developing mathematical models in inventory control it is assumed that payment will be made to the supplier for the goods immediately after receiving the consignment. However, in practice, it is found that the supplier allows a certain fixed period to settle the account. During this fixed period no interest is charged by the supplier, but beyond this period interest is charged under the terms and conditions agreed upon and, moreover, interest can be earned on the revenue received during the credit period. In this paper an attempt has been made to obtain the optimum order quantity of deteriorating items under a permissible delay in payments. A numerical example is also given.
