Retailers often experience stockouts when a supplier fails to deliver an order. In this paper, we identify the optimal procurement policy of a multi-product retailer in the presence of possible supply disruptions. Our analysis reveals that, in anticipation of potential supply disruptions, a retailer would typically benefit from ordering more units from a reliable supplier and fewer units from an unreliable one. Furthermore, the total number of units ordered may increase when there is supply disruption risk. As a result, the retailer may overstock some items. However, there are situations in which a retailer would optimally respond to supply uncertainty by consolidating its selling strategy around the unreliable supplier’s product. Under such a strategy, we find the surprising result that the retailer reduces the amount it orders from a reliable supplier as an unreliable seller becomes even less reliable. We also explore how supply disruptions can affect a retailer’s optimal pricing strategy. We find that under certain conditions, it is beneficial for a retailer to lower its price of a substitute product when one supplier fails to deliver its product. Finally, we find that, on net, consumers may benefit from supply uncertainty even though supply disruptions eliminate access to a desirable product.

当供应商未能交付订单时，零售商经常会遇到缺货的情况。在本文中，我们确定了存在可能的供应中断的多产品零售商的最佳采购策略。我们的分析表明，在预期潜在供应中断的情况下，零售商通常会受益于从可靠供应商订购更多产品和从不可靠供应商订购更少产品。此外，当存在供应中断风险时，订购的单位总数可能会增加。因此，零售商可能会积压某些商品。然而，在某些情况下，零售商会通过围绕不可靠供应商的产品整合其销售策略来最佳应对供应不确定性。在这样的策略下，我们发现了一个令人惊讶的结果，即零售商减少了从可靠供应商那里订购的数量，因为不可靠的卖家变得更不可靠了。我们还探讨了供应中断如何影响零售商的最佳定价策略。我们发现，在某些条件下，当一个供应商未能交付其产品时，零售商降低替代产品的价格是有益的。最后，我们发现，从净值来看，即使供应中断导致无法获得理想产品，消费者也可能从供应不确定性中受益。当一个供应商未能交付其产品时，零售商降低替代产品的价格是有益的。最后，我们发现，从净值来看，即使供应中断导致无法获得理想产品，消费者也可能从供应不确定性中受益。当一个供应商未能交付其产品时，零售商降低替代产品的价格是有益的。最后，我们发现，从净值来看，即使供应中断导致无法获得理想产品，消费者也可能从供应不确定性中受益。
