Many intensive care units (ICUs) face overcrowding. One response to this overcrowding is to bump ICU patients to other departments of the hopsital to make room for new patient arrivals. Such bumping clearly has the potential to reduce quality care. In this paper we develop a stochastic model of...

We examine how operational changes in customer flows in retail stores affect the rate of COVID-19 transmission. We combine a model of customer movement with two models of disease transmission: direct exposure when two customers are in close proximity and wake exposure when one customer is in the...

We consider the work flow in a medical teaching facility, examining the process that involves an initial patient exam by a resident physician, a subsequent conference between the resident and the attending physician, and the attending physician’s visit with the patient. We create an analytical...

Intensive Care Units (ICUs) play a vital role in hospitals and they often have capacity strain. Using data from a major teaching hospital, we empirically examine the effect of ICU capacity strain on patient discharge. Our data has a dynamic measure of patient health status, allowing us to study...
