Cardiology, On the first glance, the answer is obvious: it's a system which purpose is to help with queuing. 1 Queueing Theory Basics (see Hillier and Lieberman 17.2,7) Learning Objectives 1.Know the goals of queueing theory. Patient queues are prevalent in healthcare and wait time is one measure of access to care. It can be difficult anticipating use queuing, Queuing Theory - . We illustrate Queueing Theory-an analytical tool that has provided many insights to service. The quantity oriented healthcare services meaning caring more patients are not good at meeting quality parameters of healthcare services. cause problems in service delivery. But not providing enough service capacity results in excessive waiting time and cost. fundamental of queuing theory. The study of optimal queuing systems in healthcare is crucial at such a time as this to help decongest the system, and minimize financial and health-related risks associated with long waiting queues.
