我们考虑在具有两个需求子周期的分散系统中两个商店之间的预防性转运。补货订单在第一个子周期之前发出，商店可以在子周期之间进行相互转运。我们证明转运决策有一个主导策略，称为控制带保留转移策略，在该策略下，每个商店选择转运进或出的数量，以将其第二子期起始库存水平保持在称为控制带的范围内。我们证明最优补货策略是一个阈值策略，其中阈值取决于其他商店的容量水平。最后，我们证明不存在协调去中心化供应链的转移价格。我们的研究还解释了预防性转运和紧急转运之间的许多差异，包括最优转运政策的差异以及协调系统的转运价格是否存在。 © 2010 Wiley periodicals, Inc. 海军研究后勤部，2010
We consider preventive transshipments between two stores in a decentralized system with two demand subperiods. Replenishment orders are made before the first subperiod, and the stores may make transshipments to one another between the subperiods. We prove that the transshipment decision has a dominant strategy, called a control‐band conserving transfer policy, under which each store chooses a quantity to transship in or out that will keep its second‐subperiod starting inventory level within a range called a control band. We prove that the optimal replenishment policy is a threshold policy in which the threshold depends on the capacity level at the other store. Finally, we prove that there does not exist a transfer price that coordinates the decentralized supply chain. Our research also explains many of the differences between preventive and emergency transshipments, including differences in the optimal transfer policies and the existence or nonexistence of transfer prices that coordinate the system. © 2010 Wiley Periodicals, Inc.
