中文摘要：

以两单链的集群式供应链为背景，考察一供应链零售商的紧急库存补充渠道来自于另一供应链零售商的跨间库存协调问题。建立了没有单链（补充链）约束和存在单链约束条件下的跨链间库存合作模型。并用系统优化理论来寻求被补充供应链的正常渠道订货量和紧急补充量，以达到降低库存水平，提高整体利润。通过实例分析发现：商品零售价格和库存费率较高，以及订货间隔期短，紧急库存补充价格较低时，有促使集群供应链跨链间库存协作的倾向。

英文摘要：

On the basis of cluster supply chains consisting of tWO single ones, the retailer ot one supply chain transshipping stock from the retailer of the other chain is taken into account for exploring across-chain inventory coordination. The two across-chain inventory coordination models with and without single chain （suppl- ying） constraint are built. To reduce stock and increase profits, the regular replenishment quantity and emergency transshipment quantity for the receiving chain are found through utilizing systematic optimization theory. The experiment results show that across-chain inventory coordination can be promoted by higher retail price, higher inventory rate, shorter order interval and lower emergency transshipment price.
