我们研究了有限规划期内动态确定性需求环境下的转运策略。这是第一次在动态或确定性背景下审查转运问题。我们考虑一个系统的两个地点补充他们的库存从一个单一的供应商，并在位置之间的转运是可能的。我们的模型包括固定（可能是联合）和可变补货成本，固定和可变转运成本，以及每个地点的持有成本和地点之间的转运成本。问题是要确定有多少补充和多少转运每个时期，因此这项工作可以被看作是一个综合的转运问题，在一个静态随机设置和多位置动态确定性批量问题。我们提供了有趣的结构特性的最优政策，提高我们的理解，激励转运的重要问题，使我们能够开发一个有效的多项式时间算法获得的最优策略。通过探索使用转运的原因，我们使从业者能够设想使用这种策略节省的来源，从而激励他们将其纳入他们的补给策略。John Wiley & Sons，Inc.海军研究后勤48：386-408，2001年
We investigate the strategy of transshipments in a dynamic deterministic demand environment over a finite planning horizon. This is the first time that transshipments are examined in a dynamic or deterministic setting. We consider a system of two locations which replenish their stock from a single supplier, and where transshipments between the locations are possible. Our model includes fixed (possibly joint) and variable replenishment costs, fixed and variable transshipment costs, as well as holding costs for each location and transshipment costs between locations. The problem is to determine how much to replenish and how much to transship each period; thus this work can be viewed as a synthesis of transshipment problems in a static stochastic setting and multilocation dynamic deterministic lot sizing problems. We provide interesting structural properties of optimal policies which enhance our understanding of the important issues which motivate transshipments and allow us to develop an efficient polynomial time algorithm for obtaining the optimal strategy. By exploring the reasons for using transshipments, we enable practitioners to envision the sources of savings from using this strategy and therefore motivate them to incorporate it into their replenishment strategies. © 2001 John Wiley & Sons, Inc.
