We examine a possibly capacitated, periodically reviewed, single-stage inventory system where replenishment can be obtained either through a regular fixed lead time channel, or, for a premium, via a channel with a smaller fixed lead time. We consider the case when the unsatisfied demands are backordered over an infinite horizon, introducing the easily(More)
Companies in a variety of industries (e.g., airlines, hotels, theaters) often use last-minute sales to dispose of unsold capacity. Although this may generate incremental revenues in a short term, the long-term consequences of such a strategy are not immediately obvious: more discounted last-minute tickets may lead to more consumers anticipating the discount(More)
In many services, the quality or value provided by the service increases with the time spent with the customer. However, longer service times also result in longer waits for customers. We term such services, in which the interaction between quality and speed is critical, as customer-intensive services. In a queueing framework, we parameterize the degree of(More)
W e study how consumers with waiting cost disutility choose between two congested services of unknown service value. Consumers observe an imperfect private signal indicating which service facility may provide better service value as well as the queue lengths at the service facilities before making their choice. If more consumers choose the same service(More)
Firms that rely on functioning mission-critical equipment for their businesses cannot a¤ord signi…cant operational downtime due to system disruptions. To minimize the impact of disruptions , a proper incentive mechanism has to be in place so that the suppliers provide prompt restoration and recovery services to the customer. A widely adopted incentive(More)
In the Operations Research queue-joining literature, beginning with Naor (1969), the queue joining probability is monotonic decreasing in the queue length; the longer the queue, the fewer consumers join. Recent academic and empirical evidence indicates that queue-joining probabilities may not always be decreasing in the queue length. We provide a simple(More)
Consumers often purchase goods that are " hard to find " to conspicuously display their ex-clusivity and social status. Firms that produce such conspicuously consumed goods such as designer apparel, fashion goods, jewelry, etc., often face challenges in making optimal pricing and production decisions. Such firms are confronted with precipitous tradeoff(More)
We study how a high quality service firm selects a service rate differently than a low quality service firm when the firm cannot communicate its service value or service rate to its customer base. As a result, potential customers may take the queue length upon arrival into account when assessing the service value before joining the queue for service. We(More)
