【摘要】：以现实中实物商品供应链的商业信用额度限制为背景,给出了一种新的条件延期还款策略。假设需求率从到货开始线性依赖于即时库存量,直到库存水平到达一个确定的值Qs后,需求率变为常数。为防止零售商大量订货造成供应商资金的过度占用,供应商采用反向条件延期付款策略,即零售商在订货量小于等于某个确定值Q1时,可以延迟支付货款;反之,则必须立即支付所有货款。通过分析给出了该问题所有可能的决策区间,整理出零售商利润函数的四种不同形式,结合数学证明得到了每个目标函数的解析性质并给出了相应的命题,由此设计了求解步骤以有效地确定零售商的最优决策。数值算例表明在这种决策情境下零售企业完全可能主动放弃延时还款而增加订货量以获得更大的利润,由此得到一些有价值的管理启示。
[Abstract]:This paper presents a new conditional deferred repayment strategy under the background of the commercial credit limit of the physical goods supply chain. It assumes that the demand rate linearly depends on the immediate inventory from the arrival of goods. Until the inventory level reaches a certain value Qs, the demand rate becomes constant. In order to prevent the retailer from overusing the supplier's funds, the supplier adopts the reverse conditional deferred payment strategy. That is, the retailer can delay payment when the order quantity is less than or equal to a certain value Q1; On the contrary, all payment must be paid immediately. Through analysis, all possible decision intervals of this problem are given, and four different forms of retailer profit function are sorted out. The analytic properties of each objective function are obtained by mathematical proof and the corresponding propositions are given. A numerical example shows that the retailer can give up the delay repayment and increase the order quantity in order to gain more profit. From this some valuable management enlightenment.

【正文快照】： 0引言实物商品分销渠道内由于市场竞争和产品替代性的增强,供应商为了维持其产品的市场份额,在与零售商签订商业合同时,必须考虑的两个因素是:延期支付货款的条款(商业信用期/延时还款期),以及零售阶段的货架展示量。特别地对于某些商品而言,货架展示量直接影响到产品的需求速
