Inventory Management with Auctions and Other Sales Channels: Optimality of (s, S) Policies
研究有固定订货成本的定期盘点库存补货问题，证明在拍卖等多种销售机制下(s, S)策略仍然最优，拓展了该策略的适用范围。
We study periodic-review inventory replenishment problems with fixed ordering costs, and show the optimality of (s, S) inventory replenishment policies. Inventory replenishment is instantaneous, i.e., the lead time is zero. We consider several sales mechanisms, e.g., auction mechanisms, name-your-own-price mechanisms, and multiple heterogeneous sales channels. We prove this result by showing that these models satisfy a recently-established sufficient condition for the optimality of (s, S) policies. Thus, this paper shows that the optimality of (s, S) policies extends well beyond the traditional sales environments studied so far in the inventory literature.
