  Queueing theory - Wikipedia, the free encyclopedia
Queueing theory (also commonly spelled queuing theory) is the mathematical study of waiting lines (or queues).
Queueing theory is directly applicable to intelligent transportation systems, call centers, PABXs, networks, telecommunications, server queueing, mainframe computer queueing of telecommunications terminals, advanced telecommunications systems, and traffic flow.
For queueing theory, it is most convenient to work with probability distributions which exhibit the memoryless property, as it vastly simplifies the mathematics involved.

 NationMaster - Encyclopedia: Queueing theory
In probability theory, memorylessness is a property of certain probability distributions: the exponential distributions and the geometric distributions.
In queueing theory, Littles result, theorem, or law says: The average number of customers in a stable system (over some time interval) is equal to their average arrival rate, multiplied by their average time in the system.
Queue areas are areas in which people queue (first-come, first-served), that is they wait in line for something.

 Queueing Theory
Mathematical techniques, including probability theory, used in operations or operational research to identify, illustrate and, it is hoped, influence the characteristics of queues, whether of people, materials, work-in-progress, etc. The object is to find the best way of planning the sequence of events so that bottlenecks can be avoided.
Queueing theory deals with problems of congestion in which two opposing pressures must be balanced.

Queueing theory is an applied mathematical discipline dealing with the performance of technical systems (referred to as queueing systems) for processing flows of customers.
Recently, the interest in queueing theory has been revived, not only as a result of new, related applied problems, such as the development and application of computers, but also due to the advent of new mathematical approaches to their solution.
The aim of this monograph is to familiarise readers with certain tools of the queueing theory (including its latest techniques) and the results of their application.

A message queue is a set of memory locations that provide temporary storage for data that are being passed from process to process (or to/from interrupt service software).
So the number of messages remaining in the queue at the end of the burst is: L = (P--C)*T. Since the queue gets longer as time advances through the burst, the length of the queue at the end of the burst is the maximum length of the queue during the burst.
In the general case, the point at which the queue is longest could be in the middle of the burst or two-thirds of the way through a burst or anywhere else.

 A.2 About Queueing Theory
Queueing theory is a broad area of mathematics that attempts to model the behaviour of queues (as the name would suggest).
Queues are usually drawn as in Figure A.1.
Additionally for queues that have finite buffers we can calculate the amount of traffic that is successfully accepted into the buffers.

 queueing theory - a definition from Whatis.com   (Site not responding. Last check: 2007-11-07)
In computer science, queueing theory is the study of queues as a technique for managing processes and objects in a computer.
A queue can be studied in terms of: the source of each queued item, how frequently items arrive on the queue, how long they can or should wait, whether some items should jump ahead in the queue, how multiple queues might be formed and managed, and the rules by which items are enqueued and dequeued.
The queues that a computer manages are sometimes viewed as being in stacks.

 Queuing Theory Discussion
Using the word "Queue", which is more common in British than American English and means "a line up" or "to form a line", a closely reasoned body of mathematical theory has been developed to describe this common human activity - theory applicable to normal economic activity.
The origination of the formal study of Queuing Theory is credited to A. Erlang, a Danish telephone engineer who in the 1920's was attempting to predict telephone call service.
Queuing Theory deals mathematically with both the regularities and irregularities of such systems - ultimately identifying occurrences of congestion (resulting from irregularities) and offering avenues for improving efficiency, as well as producing specific numerical data for further application.

Changing the queue discipline (the rule by which we select the next customer to be served) can often reduce congestion.
The first queueing theory problem was considered by Erlang in 1908 who looked at how large a telephone exchange needed to be in order to keep to a reasonable value the number of telephone calls not connected because the exchange was busy (lost calls).
Note that this is an M/M/2/4 queueing system as we have two servers and a total number of customers in the system of 4 (2 being served, 2 waiting in the queue for service).
