Queuing Theory A flow of "customers" from infinite/finite population towards the service facility forms a queue or waiting line on account of lack of capability to serve them all at a time.These "customers" may be persons waiting at a railway booking office,these may be machines waiting to be repaired or letters arriving at a typist's desk. Queuing Theory is the mathematical study of waiting lines,or queues.It examines every component of waiting in line to be served, including the arrival process, service process, number of servers, number of system places and the number of customers. It is used to develop more efficient queuing systems that reduce customer wait times and increase the number of customers that can be served. Applications Queuing theory has its origins in research by Agner Krarup Erlang when he created models to describe the Copenhagen telephone exchange. The ideas have since seen applications including telecommunications, traffi...
