Transshipments: An emerging inventoryrecourse to achieve supplychain leagility

Supply chain designs are constrained by the cost-service trade-off. Cost minimization typically leads to physically efficient or lean supply chains at the expense of customer responsiveness or agility. Recently, the concept of leagility has been introduced. Research on leagility, defined as the capability of concurrently deploying the lean and agile paradigms, hinges heavilyon the identification of the decoupling point, which, in turn, is enabled bypostponement. Postponement strategies, however, present a cross-functional challenge for implementation. As a tactical solution to achieve leagility without postponement, we introduce transshipments, which represent a common practice in multi-location inventory systems involving monitored movement of stock between locations at the same echelon level of the supply chain. Through a series of models, we establish how transshipments can be used to enhance both agilityand leanness. r 2002 Elsevier Science B.V. All rights reserved.
