研究了在允许延迟付款条件下，指数恶化型产品的经济订货批量的确定问题。延迟付款取决于订购的数量。当订单数量少于允许延迟付款的数量时，必须立即支付产品的款项。否则，允许使用固定贸易信贷期。基于上述论点，本文结合了Hwang和Shinn（Comput. Oper Res.24（1997）539）和Khouja和Mehrez（J.Manuf.Systems 15（1996）334）。此外，目标函数被建模为一个总的可变成本最小化问题。提出了一种确定经济订货批量的算法。最后通过算例说明了本文的结果。最后，本文的结果推广了一些已发表的结果。
This paper deals with the problem of determining the economic order quantity for exponentially deteriorating items under the conditions of permissible delay in payments. The delay in payments depends on the quantity ordered. When the order quantity is less than at which the delay in payments is permitted, the payment for the product must be made immediately. Otherwise, the fixed trade credit period is permitted. Based upon the above arguments, this paper incorporates both Hwang and Shinn (Comput. Oper. Res. 24 (1997) 539) and Khouja and Mehrez (J. Manuf. Systems 15 (1996) 334) under above conditions. In addition, the objective function is modeled as a total variable cost-minimization problem. An algorithm to determine the economic order quantity is developed. Examples are solved to illustrate the results given in this paper. Finally, the results in this paper generalize some already published results.
