Markov decision processes (MDPs) in queues and networks have been an interesting topic
in many practical areas since the 1960s. This paper Provides a detailed overview on this …

In hospitals, Step Down Units (SDUs) provide an intermediate level of care between the
Intensive Care Units (ICUs) and the general medical‐surgical wards. Because SDUs are …

Despite the fact that hospital care is often delivered in successive stages, current healthcare
scheduling and capacity planning methods usually treat different hospital units in isolation …

Tandem queues have been used to model congestion in a wide variety of systems such as
communication networks, manufacturing systems, supply chains and traffic flows. This paper …

In this technical note, we study a finite double-sided queue with multiple customer types,
where two-sided arrivals follow independent Poisson processes. Customers arrive to one …

Problem definition: Multistage service is common in healthcare. One widely adopted
approach to manage patient visits in multistage service is to provide patients with visit …

We consider the controlled tandem queuing network with two single-server finite-length
queues with non-stationary Poisson input flow of packets. The first station controls the …

Step Down Units (SDUs) provide an intermediate level of care between the Intensive Care
Units (ICUs) and the general medical-surgical wards. Because SDUs are less richly staffed …

A tandem queuing system that contains two single-channel stations with finite buffers and
allows blocking of the first server is considered. The first station receives nonstationary …

The gap between medical research on diagnostic testing and clinical workflow can lead to
rejection of valuable medical research in a busy clinical environment due to increased …
