Care services within the patient rooms are the most critical and time consuming processes in patient care deliveries in emergency department, clinics, and other healthcare facilities. In this paper, we introduce a Markov chain model to study such processes. A closed, parallel, and reentrant network with limited resources is used to model the process.(More)
In this paper, we propose an analytical framework for modeling and analysis of hospital emergency departments (ED). Using such a framework, we intend to develop methods that can be used to improve ED performance through redistributing limited resources and through identifying and mitigating bottlenecks. Specifically, the following problems will be(More)
In this paper, we introduce a Markov chain model to study the care delivery services within the patient rooms. Closed formulas to evaluate the patient length of stay and staff utilizations are developed. To illustrate the method, a numerical example is presented and monotonic properties are discussed. Such a model provides a quantitative tool for healthcare(More)
