We consider the partitioning of care types into wings from the perspective of a hospital
administrator who wishes to optimize the use of a fixed number of beds that provide services …

Observable priority queues are prevalent in practice and create incentives for utility-
maximizing customers to abandon after joining. However, the literature has so far ignored …

Queuing systems with customers' impatience are highly applicable in many real life
situations, for instance, in grocery stores, banks, hospitals, barber shops, call centres, online …

We consider Markovian multi-server queues with two types of impatient customers: high-and
low-priority ones. The first type of customer has a non-preemptive priority over the other type …

We study systems with two classes of impatient customers who differ across the classes in
their distribution of service times and patience times. The customers are served on a first …

During the COVID-19 pandemic, the most important thing was to control the overall infection
rate. To achieve this goal, social managers can choose to use vaccines with different …

This article considers computational procedures for the waiting time and queue length
distributions in stationary multi-class first-come, first-served single-server queues with …

We propose a model of rational reneging based on observing queue movements.
Customers often join a queue and observe it move as they wait, and may decide to renege if …

In this paper, we analyze a discrete-time queueing model with two types (classes) of
customers and two servers, one for each customer class. Although each server can only …

We consider the FCFS $ M/H_2/n+ M $ queue in the Halfin-Whitt heavy traffic regime. It is
known that the normalized sequence of steady-state queue length distributions is tight and …
