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...

We model the optimal disposition decision for product returns. The manager decides which product returns to accept for processing at the remanufacturing facility, and which ones to sell immediately as-is at a salvage value. High congestion levels in the remanufacturing facility delay the sale of...
