我们研究了一种库存系统,其中客户在经历库存缺货后可能会离开卖方市场。传统上,研究人员和从业者假设单一惩罚成本来模拟这种厌恶缺货的客户行为。最近,一批研究人员明确模拟了这种客户行为并支持传统的惩罚成本方法。我们通过研究服务相关需求的统计学习来丰富这一文献。 我们建立并解决了四个模型:基线模型,卖方可以观察需求分布;第二种模型,卖方无法观察需求分布,但通过统计了解需求分布;第三种模式,卖方可以通过学习或付费来获取需求分布的准确信息;第四种模型,超出可用库存的需求会丢失且未被观察到。有趣的是,我们发现所有四个模型都支持传统的惩罚成本方法。该结果证实了在存在需求学习的情况下使用与状态无关的缺货惩罚成本。更引人注目的是,前三个模型隐含了相同的缺货惩罚成本,该成本大于最后一个模型隐含的缺货惩罚成本。
We study an inventory system wherein a customer may leave the seller's market after experiencing an inventory stockout. Traditionally, researchers and practitioners assume a single penalty cost to model this customer behavior of stockout aversion. Recently, a stream of researchers explicitly model this customer behavior and support the traditional penalty cost approach. We enrich this literature by studying the statistical learning of service-dependent demand. We build and solve four models: a baseline model, where the seller can observe the demand distribution; a second model, where the seller cannot observe the demand distribution but statistically learns the demand distribution; a third model, where the seller can learn or pay to obtain the exact information of the demand distribution; and a fourth model, where demand in excess of available inventory is lost and unobserved. Interestingly, we find that all four models support the traditional penalty cost approach. This result confirms the use of a state-independent stockout penalty cost in the presence of demand learning. More strikingly, the first three models imply the same stockout penalty cost, which is larger than the stockout penalty cost implied by the last model.
