An Introduction to Queuing Theory

Jul 09, 2018· Queuing theory is the mathematical study of queuing, or waiting in lines.Queues contain customers (or "items") such as people, objects, or information. Queues form when there are limited resources for providing a service.For example, if there are 5 cash registers in a grocery store, queues will form if more than 5 customers wish to pay for their items at the same time.
