货架和仓库商品共同影响需求的供应链延期支付协调

Supply Chain Coordination by Delay in Payments with a Stock-dependent Demand Rate

针对单一制造商和单一零售商组成的供应链,研究了需求受货架和仓库库存水平共同影响的企业间延期支付协调问题.首先根据制造商主导的Stackelberg对策结构,对供应链成员间的决策问题进行了分析;然后为制造商提出了一个改善整个供应链运作效率的延期支付策略,研究结果表明该延期支付模型不仅能提高制造商的利润,而且能提高零售商的利润.最后给出了数值例子,并对模型参数灵敏度进行了分析.

A supply-demand system coordination problem with a stock-dependent demand is considered by delay m payments, where the system is composed of a single manufacturer with a single retailer. First, the problem is analyzed as a Stackelberg game in which the manufacturer declares its time for delay in payments to the retailer and then the retailer follows by selecting its order quantity. Then a delay in payments policy is proposed for the manufacturer that could make channel efficiency better , and the results verify that this policy can not only make the manufacturer＇s profit better but also enhances the retailer＇s profit ,more importantly it can coordinate the supply chain perfectly. At last, numerical examples and sensitive analysis of the parameters are presented to illustrate the developed model.
