Inventory Control with Information About Supply Conditions
构建了一个包含供应系统马尔可夫模型的库存控制模型，发现最优策略结构与标准模型相同但参数动态调整，且较长的提前期不一定意味着更多库存。
This paper presents an inventory-control model which includes a Markovian model of the supply system. As that system evolves over time, so do the replenishment leadtimes. The optimal policy has the same structure as in standard models, but its parameters change dynamically to reflect current supply conditions. In this setting, contrary to conventional wisdom, a longer leadtime does not necessarily imply more inventory. The leadtime is important, but so is a concept we call order coverage.
