Abstract

Transshipment is an effective method for reducing mismatches between supply and demand among retailers. Consumers attempting to purchase out-of-stock items may wait for transshipment, purchase at another store, or choose not to buy. In this paper, the consumer behavioral heterogeneity is characterized using the transshipment request rate and consumer switching rate. It affects the replenishment and transshipment decisions, as well as the system profits. The inventory replenishment and transshipment decisions are studied in both centralized and decentralized two-location inventory systems with consumer behavioral heterogeneity. We characterize optimal replenishment decisions in a centralized system, prove the existence of a unique Nash equilibrium in a decentralized system with a specific demand distribution, and determine the coordinating transshipment price for some decentralized systems. In numerical studies, the performance of various systems is analyzed for consumers with identical (symmetric) or differing (asymmetric) behavior between retailers. For scenarios with symmetric consumers, a higher transshipment request rate and consumer switching rate resulted in increased total profit in all systems. For scenarios with asymmetric consumers, the retailer with the higher consumer switching rate should reduce ordering in a centralized system but increase ordering in a decentralized system. Moreover, the retailer with the higher transshipment request rate reduces ordering to increase profit, whereas the other retailer increases order quantity yet earns less profit.

具有消费者行为异质性的联合库存和转运决策
转运是减少零售商之间供需不匹配的有效方法。试图购买缺货商品的消费者可能会等待转运、在其他商店购买或选择不购买。本文利用转运请求率和消费者切换率来表征消费者行为的异质性。它影响补货和转运决策,以及系统利润。研究了具有消费者行为异质性的集中和分散两地库存系统中的库存补货和转运决策。我们刻画了集中系统中的最优补货决策,证明了具有特定需求分布的分散系统中存在唯一的纳什均衡,并确定了一些分散系统的协调转运价格。在数值研究中,针对零售商之间行为相同(对称)或不同(不对称)的消费者,分析了各种系统的性能。对于对称消费者的场景,较高的转运请求率和消费者切换率导致所有系统的总利润增加。对于消费者不对称的场景,消费者切换率较高的零售商应该在集中式系统中减少订单,但在分散式系统中增加订单。此外,转运请求率较高的零售商减少订单以增加利润,而另一零售商增加订单数量但获得的利润较少。
