在零售商存在资金不足和顾客需求随机情况下，以报童模型为基础，针对变质品构建了供应链金融问题和ACC支付模式（提前支付Advance、现金支付Cash和信用支付Credit）相结合的零售商订货模型，即零售商与供应商、融资机构合作条件下的模型。研究表明，零售商会随着最优订货批量和最低期望成本的增加和降低趋势，进而调整订货量，从而规避供大于求的风险，最终降低总的期望成本。同时供应商可以适当调整支付比例，让零售商来分担坏账和商品变质风险。
Objectives:With the intensification of market competition, enterprises are facing a growing number of market risks and financial pressure, shortage of funds will become the norm,which restricts the rapid development of enterprises. Considering the lack of retail funds and randomness of customer demand, an ordering model for deteriorating items that combines supply chain finance and ACC payment (advance payment, cash payment and credit payment) is constructed on the basis of the newsboy model. Methods:The new model gives the specific interest income and interest cost of retailer based on different payment proportionality, payment cycle and order cycle. In addition, it combines with changes in inventory model to obtain the metamorphism cost and opportunity cost. In this model, shaortage is allowed, the sales of the product, financing interest and credit period are also considered, which is under the cooperation of retailers, suppliers and financing institutions. Results:In this paper, the order quantity is set as the independent variable and the minimum expected cost as the objective function. Then it proves the existence and reliability of the optimal solution and gives the calculation method of the optimal solution.Conclusions:The study shows that the retailer will adjust the order quantity with the increase and decrease of the optimal order quantity and the minimum expected cost, so as to avoid the risk of oversupply.And the supplier can adjust the payment ratio appropriately to let the retailer share the risk of bad debts and commodity deterioration.
