摘　　要：在装配制造供应链中,为了避免供应中断的风险,制造商往往向多个供应商采购相同的零部件,即采用多源供货方式。近年来,随着越来越多的装配制造企业采用准时制(Just in time,JIT)方式进行生产运作,Supply-Hub模式作为一种有效支持JIT运作的供应物流运作模式,在装配制造供应链中也逐渐得到了广泛应用。Supply-Hub不仅是供应链中零部件物流的枢纽节点,更重要的是,它还起到信息集中平台的作用,掌握各方供应商的库存和补货信息,这使供应相同零件的供应商之间实现横向协同运作成为可能。目前,虽然已有较多关于多源供货问题的研究文献,但仍还没有文献涉及供应同种零件的供应商之间横向协同的问题。基于Supply-Hub模式,通过数学建模分析,研究一种两个供应相同零件的供应商利用Supply-Hub,在横向共享库存信息条件下的协同补货策略,并通过算例对该协同补货策略的有效性进行验证分析。研究结果表明,运用横向协同补货策略,在不降低系统服务水平的情况下,可以明显降低供应链系统的总成本。In the assembly supply chain,manufacturers often source from more than one supplier to avoid supply disruption risks.As increasing manufacturers initialize their just in time（JIT） systems,Supply-Hub becomes a la mode in the assembly systems to support the JIT production.Supply-Hub is not only a logistics hub,but also an information platform,and it masters the inventory and replenishment information of all suppliers.That makes it possible that the suppliers coordinate horizontally.But till now,there is few paper focus on horizontally coordinated replenishment between suppliers who supply the same component although there are lots of research on the problems of multi-sourcing.Therefore,based on Supply-Hub mode,a horizontally coordinated dual-Sourcing policy is studied through establishing the mathematical model,and the validity of the policy was demonstrated by a numerical example.The conclusion indicates that the total cost of supply chain can be decreased obviously while the sevice level is not reduced by using this horizontally coordinated replenishment policy.
