Case Study Week: Day One

FlexSim Case Study Week

The Design of an Autonomic Controller for Self-Managed Emergency Departments

On day one of Case Study Week, we’re going to examine a paper titled “The Design of an Autonomic Controller for Self-Managed Emergency Departments” by Dr. Serene Al-Momen and Dr. Daniel A. Menascé, who both have connections to George Mason University in Fairfax, VA.

The paper can be viewed at this location.

In their research, Almomen and Menascé sought to present a design to an autonomic controller for a self-managed emergency department, which would serve to adjust the parameters of the emergency department so that a certain level of service is always met.

FlexSim HC was used to simulate an emergency department that consisted of a finite number of resources; the model contained three unique patient tracks. The researchers used results from their simulation model and a combinatorial search algorithm to attempt to obtain “a near-optimal configuration… for the ED without performing an exhaustive search of the space of all possible configurations.”
