Discussion Slide -1 Define Queuing Model or Queuing Theory Queuing theory is the mathematical study of waiting lines (or queues) that enables mathematical analysis of several related processes, including arriving at the (back of the) queue, waiting in the queue, and being served by the Service Channels at the front of the queue.

Today’s queueing theory is indebted to the emergence and growth of operations research after 1945 yet the origins of the field predate those of operations research, extending back by some measures to Siméon Denis Poisson’s 1837 work on criminal cases. 1948).
