我们考虑一个有能力的供应系统，生产一个单一的项目，是由几类客户的需求。不同的客户类别可能有不同的缺货成本，因此库存分配成为一个关键的决策问题。我们将供应系统建模为多客户按库存生产的排队系统。使用动态规划，我们证明了最优分配策略具有简单直观的结构。此外，我们提出了一个有效的算法来计算这个最优分配策略的参数。最后，对于一个典型的供应链设计问题，我们说明，忽略库存分配维度-一个经常遇到的简化假设-可能会导致不正确的管理决策。
We consider a capacitated supply system that produces a single item that is demanded by several classes of customers. Each customer class may have a different backorder cost, so stock allocation arises as a key decision problem. We model the supply system as a multi customer make-to-stock queue. Using dynamic programming, we show that the optimal allocation policy has a simple and intuitive structure. In addition, we present an efficient algorithm to compute the parameters of this optimal allocation policy. Finally, for a typical supply chain design problem, we illustrate that ignoring the stock allocation dimension--a frequently encountered simplifying assumption--can lead to incorrect managerial decisions.
