基于ACC支付模式的两层信用支付的EOQ模型

An EOQ model under two levels of trade credit with ACC payments

为了避免坏账,同时刺激下游零售商订购批量,上游供应商要求零售商采取ACC支付模式(提前支付advance、现金支付cash和延期支付credit).针对顾客资金情况,将顾客分为如下两类:第1类顾客资金充足,顾客会提前支付部分比例的货款,同时获得价格折扣,剩余货款采取延期支付的方式,这类顾客不仅享受价格折扣,同时享受延期支付策略;第2类顾客资金不足,顾客会采取部分货款货到付款,剩余货款采取延期支付的方式,这类顾客仅享受延期支付策略.构建由1个供应商与1个零售商和两类资金情况不同的顾客构成的两层信用支付供应链库存模型,证明最优解的存在性和唯一性.研究表明,零售商可以通过提高销售价格,争取更大的价格折扣,缩短零售商提前支付货款的时间期限,减少提前支付货款的比例等策略,以实现降低其年均成本.

In order to avoid bad debt, while stimulate downstream retailers to order batches, upstream suppliers require retailers to adopt ACC payment patterns(advance, cash and credit). According to customers’ funding situations, we divide the customers into the following two categories: One type of customers who have sufficient funds are able to pay part of the payment in advance and obtain a price discount, and the rest payment will be credited, this type of customers enjoy not only the price discount but also the credit payment strategy;the other type of customers who have insufficient funds will take part of the payment of cash on delivery, the remained payment by credit payment, so this type of customers only enjoy the credit payment strategy. On that basis, a two-tier credit payment supply chain inventory model which consists of one supplier, one retailer and two types of customers with different preferences is established to prove the existence and uniqueness of the optimal solution. Numerical examples are used to analyze the sensitivity of the key parameters. The research shows that retailers can increase the sales price, strive for greater price discount, shorten the time period for retailers to pay for goods in advance, and reduce the proportion of payment in advance to achieve a lower annual average cost.
