1. A Short Introduction to Queueing Theory   Author :   Andreas Willig ,   Technical University Berlin ,   Telecommunication Networks Group   Publication Date : July 21, 1999   Book Excerpts:   This document is intended to be a short introduction to the field of queueing theory, serving as a module within the lecture   Leistungsbewertung von Kommunikationsnetzen   of   Prof. Adam Wolisz from the   Telecommunication Networks Group   at   Technical University Berlin . It covers the most important queueing systems with a single service center, for queueing networks only some basics are mentioned. This script is neither complete nor error free.   In this script most of the mathematical details are omitted, instead often "intuitive" (or better: prosaic) arguments are used. Most of the formulas are only used during a derivation and have no numbers, however, the important formulas are numbered. The author does not ...

Basics of Operational Research Operations research (also referred to as decision science , or management science ) is an interdisciplinary mathematical science that focuses on the effective use of technology by organizations. In contrast, many other science & engineering disciplines focus on technology giving secondary considerations to its use. Employing techniques from other mathematical sciences — such as mathematical modeling, statistical analysis, and mathematical optimization — operations research arrives at optimal or near-optimal solutions to complex decision-making problems. Operations Research is often concerned with determining the maximum (of profit, performance, or yield) or minimum (of loss, risk, or cost) of some real-world objective. Operational research encompasses a wide range of problem-solving techniques and methods applied in the pursuit of improved decision-making and efficiency. Some of the tools used by operational researchers are statistics, optimizatio...
