摘　　要：Supply-Hub作为整合管理不同供应商零件库存的供应链节点,同时也承担了供应物流协同运作管理平台的功能。本文考虑加工-装配系统中存在的因一种零件缺货而造成其它配套使用的零件滞存的问题,研究了一种基于Supply-Hub运作模式,在供应商之间可以共享补货及库存信息的条件下,供应商协同补货策略,并与供应商分散补货模式下的基本补货模型进行比较分析。通过算例验证了该补货策略能有效降低供应链系统成本以及供应商成本。The backorder of any components can not only delay the delivery of the final product but also stop other components being assembled in a production line.Backorder problems can slow the inventory turnover rates and disrupt production plans of all related suppliers.As a result,production costs can be substantially increased.These increased production costs on suppliers are considered ＂extra holding costs.＂Supply-hub is an innovative strategy that has been increasingly employed by assembly firms to meet the logistics requirements,achieve cost reduction and improve responsiveness.Supply-hubs act not only as warehouses but also as information system platforms for supply chain logistics.Utilizing the supply-hub strategy enables suppliers to share information,such as inventory and replenishment information.As a result of the information sharing mechanism,suppliers can collaborate with each other to make more accurate replenishment decisions.Collaborative operations among suppliers of different components can help minimize the system costs and accommodate the demand of assembly plants.Assumptions and a theoretical model are introduced.We assume that a supply chain consists of supply-hubs and manufacturers.The supply-hub strategy adopts the＂milk-run＂method to pick up components from these two kinds of suppliers.Suppliers＇ costs are interrelated because of the extra holding costs of matching components.A coordinated replenishment policy,designed to encourage information sharing among suppliers,needs to address the following activities：（1） Suppliers with longer lead times first decide on their replenishment quantities,and then uploads the replenishment information to the supply-hub;（2） Suppliers with shorter lead times choose their replenishment quantities based on the inventory information of other suppliers on the supply-hub platform;and（3） The supply-hub dispatches vehicles to collect components from those supplies in a predetermined quantity with＂milk-runs.＂ A unique Nash equilibrium exists s
