Every one of us now a day is compelled to take services of a bank. Let it be  purchasing a house , getting an electric connection, water connection, admitting a child in a school, taking admission in any educational institution, applying for a job every where a bank's draft, a cheque or some other method of payment is pre- required without which nothing is found possible. In other words a Bank has become a necessity of our life in one way or the other way, In case you are getting some payment from any organization you will either receive a Bank cheque or a bank draft. In order to get the hard cash in your hands you need the services of a bank. Not only receiving money, even for making payments to some one else the services of a bank are required. In these circumstances every one of us is bound to avail the services of a bank for one or the other reasons. It has generally been found that the knowledge about the banking services is not available to the general people who under

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 annotate all statements with a reference, since most of the

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

What is operations research? Explain the scope of OR.                                    [3] List the phases of OR and explain them.                                                           [3] Discuss the guideline of formulation of Linear Programming model and for         converting it into standard form?                                                                          [3]      Define the following:                                                                                         [3]             a.  Optimal solution.                    b. Unbounded solution. c.   Artificial variable.       5. A paper mill produces 2 grades of paper namely X and Y. Because of raw  material restrictions, it cannot produce more than 400 tonnes of grade X and 300            tonnes of grade Y in a week. There are 160 production hours in a week. It requires 0.2 and 0.4 hours to produce a ton of products X and Y respectively with corresponding profits of Rs.2
