A lot-sizing model with backordering under hybrid linked-to-order multiple advance payments and delayed payment
نویسندگان
چکیده
An economic order quantity model with backordering is investigated under a hybrid payment scheme. The payment scheme, which is also linked to order quantity, involves multiple advance payments as well as delayed payment. Incorporating this payment scheme can efficiently stimulate sales due to applying delayed payment; besides it provides the benefits of advance payment such as controlling the risk of cash flow. The developed model seeks to optimize the order and shortage quantities. Theoretical results are developed to determine the conditions of existence and uniqueness of the optimal solutions. Numerical examples illustrate the proposed model and solution method. 2015 Elsevier Ltd. All rights reserved.

متن کاملAn EOQ model with partial backordering and advance payments for an evaporating item
In the classic Economic Order Quantity model the purchasing cost of an order is paid at the time of its receipt. In some cases retailers ask purchasers to pay all or a fraction of the purchasing cost in advance and may allow them to divide the prepayment into several equal-sized parts. In this paper, an economic order quantity model for an evaporating item with partial backordering and partial ...

The main purpose of this paper is to investigate the optimal retailer’s lot-sizing decisions under partial payments delay within the economic order quantity (EOQ) framework. All previously published models concerned with payments delay assumed that the supplier would offer the retailer fully payments delay. However, in this paper, we assume that the supplier would offer the retailer partial pay...
