We study capacity competition in a service environment where the arrival rates are highly seasonal (e.g., lunch time rushes) and customers are time sensitive, so may depart without receiving service if the waiting time is too long. As a stepping stone for the competitive model, we begin by...

We consider a make-to-stock manufacturing system selling multiple products to price-sensitive customers. The system manager seeks to maximize the long-run average profit by making dynamic pricing, outsourcing, and scheduling decisions: First, she adjusts prices dynamically depending on the...

This paper studies a multiclass queueing system with endogenous abandonments where congestion affects customers' abandonment behavior and vice versa. Our model captures this interaction by developing two closely related models: an abandonment model and a queueing model. In the abandonment model,...

This paper studies a Geo/Geo/1 GI queue in which the abandonments are endogenous. One crucial feature of this model is that the abandonment behavior is affected by the system performance and vice versa. Our model captures this interaction by developing two closely related models: an abandonment...

ObjectivesThe objective was to derive and validate a novel queuing theory–based model that predicts the effect of various patient crowding scenarios on patient left without being seen (LWBS) rates.MethodsRetrospective data were collected from all patient presentations to triage at an urban,...
