我们在向消费者提供易腐产品并从单一供应商接收补货的零售商的背景下探索信息价值（VOI）。我们假设一个具有随机需求、销售损失和订单数量限制的定期审查模型。一旦零售商收到产品，产品的寿命是固定的和确定的，尽管供应商提供的补充产品的年龄随时间随机变化。由于产品易腐烂，任何未售出的库存在使用期限过后必须被丢弃（过期）。如果供应商没有明确告知零售商产品的年龄，那么在收到之前，产品的年龄仍然是未知的。通过信息共享，零售商可以在下订单之前了解产品的年龄，因此可以在决策中利用这些信息。我们制定零售商的补货政策，在收货时知道产品的年龄和不知道产品的年龄，并将VOI衡量为零售商在信息共享的情况下相对于没有信息共享的情况下实现的边际利润提升。我们确立了信息共享的重要性，并确定了实现实质性利益的条件。
We explore the value of information (VOI) in the context of a retailer that provides a perishable product to consumers and receives replenishment from a single supplier. We assume a periodic review model with stochastic demand, lost sales, and order quantity restrictions. The product lifetime is fixed and deterministic once received by the retailer, although the age of replenished items provided by the supplier varies stochastically over time. Since the product is perishable, any unsold inventory remaining after the lifetime elapses must be discarded (outdated). Without the supplier explicitly informing the retailer of the product age, the age remains unknown until receipt. With information sharing, the retailer is informed of the product age prior to placing an order and hence, can utilize this information in its decision‐making. We formulate the retailer's replenishment policies, with and without knowing the age of the product upon receipt, and measure the VOI as the marginal improvement in profit that the retailer achieves with information sharing, relative to the case when no information is shared. We establish the importance of information sharing and identify the conditions under which substantial benefits can be realized.
