中文摘要：

建立了需求率依赖于库存量的单一供应商与单一零售商供应链库存及协调决策模型,首先分别对渠道内双方目标函数的性质进行分析,得出分散决策时零售商的最优订货量,并证明了集中决策供应链存在唯一最优的订货批量。进一步,采用零售商非线性信用期成本的核算方式,给出了能够取得供应链协调的供应商全信用期补贴策略。通过分析协调后供应链内双方利润增加量的比值与供应商信用期决策的关系,得出协调的供应链利润的增加额不是一个常数的结论。以此为基础,提出了供应商的最小信用期加货架补贴供应链协调策略。最后通过设计求解步骤,结合数值算例验证了结论的有效性。

英文摘要：

A single-supplier-single-retailer supply chain model with inventory and coordination decisions under stock-dependent demand rate is established.The properties of the objective functions of each member in the channel are analyzed respectively,the optimal order quantity of the retailer is given,and it is proved that there exists a unique global optimal ordering quantity in the centralized supply chain.Furthermore,using the accounting method of non-linear credit period cost of the retailer,the full credit period subsidy policy to coordinate the channel of the supplier is presented.By analyzing the relationship between the coordinating credit period decision offered by the supplier and the ratio of the supplier＇s increased profit to that of the retailer＇s,it is concluded that the increased profit of the coordinated channel is not a constant.Upon this,the minimum credit period plus shelf space subsidy coordinating policy of the supplier is given.Finally,a solution procedure is established and numerical examples are conducted to verify the validity of the conclusions.
