An Optimal Policy for a Two Depot Inventory Problem with Stock Transfer
针对英国汽车零件零售商将仓库两两配对、需求无法满足时从另一仓库调货或紧急订货的问题，本文刻画了最优策略并给出参数计算方法。
Multiple depot inventory systems with stock transfer are used by many companies especially when demand is high relative to storage capacity. The key issues in such systems are how many of each item to hold at each depot and what to do if there is a demand for an item at a depot that has none of that item in stock. This study was motivated by the inventory problem faced by a UK car part retailer that groups its depots into pairs. The company's policy for dealing with a demand at a depot that cannot be satisfied from local stock is to either transfer the item from the other depot in the group or to place an emergency order. The object of this paper is to characterise an optimal policy for this problem and to propose a method of calculating the parameters of such a policy.
