Queuing theory is an area of mathematics that analyses and models the act of queuing. It is
essentially the study of how people act when they have to wait in line to make a purchase or
receive a service, as well as what sorts of queue structure move people through lines the most
efficiently, and how many people can a specific queuing arrangement process through the line
in a particular time frame. Queuing theory is significant because it helps to describe queue
characteristics such as average wait time and gives tools for queue optimization. It influences
the design of efficient and cost-effective workflow systems from a commercial standpoint. It is
used in various sectors such as telecommunication, Transportation, logistics, finance, etc.
