Motivated by empirical studies on the impact of information on abandonment in service systems, we study novel queueing models with abandonment rates that depend on the system state and the granularity of customers’ state information.We consider a two-class multi-server priority queue with...

Waiting lists offer agents a choice between types of items with associated nonmonetary prices given by required waiting times. These nonmonetary prices are endogenously determined by a tâtonnement-like price discovery process: an item's price increases when an agent queues for it, and decreases...

Problem definition: The cost of completing a line—a continuous variable—is typically studied indirectly through customers’ decisions to balk or renege from a queue—binary variables. However, these decisions only tell us whether a customer’s completion cost is above some (unknown)...

Queues are common phenomenon in different operations nowadays. This is due to the higher demand for a service compared to the supply. The high demand for the use of the banking sector has posed some significant problems which includes poor service facilities and delivery which remains an...

We consider a learning variant of a canonical scheduling problem in a multiclass many server queue with abandonment (specifically, the M_t/M/N+M and the GI/GI/N+GI queues). The objective is to minimize the long-run average class-dependent expected linear holding and abandonment costs when the...

To study the effect of congestion on the fundamental trade-off between diagnostic accuracy and speed, we empirically test the predictions of a formal sequential testing model in a setting where the gathering of additional information can improve diagnostic accuracy, but may also take time and...
