Operations Research Models Most operations research studies involve the construction of a mathematical model. The model is a collection of logical and mathematical relationships that represents aspects of the situation under study. Models describe important relationships between variables, include an objective function with which alternative solutions are evaluated, and constraints that restrict solutions to feasible values.

The last chapter in this part of the book is concerned with simulation. However, much of it is taken up with methods of generating pseudo-random numbers and random deviates from distributions, and listing simulation languages, rather than with the art of using simulation on real problems.

More emphasis on the latter, including the formulation of simulation models, would have been more in line with the gcncral aims and scope The ready question, why yet another book on operations research, is anticipated by the authors in their preface.

Their justification is that this book, in providing an introduction to several OR topics, is particularly concerned with making them easiiy comprehensible for a newcomer to the subject and this, they infer, is nol a noticeable feature of many other textbooks.

They aspire to meet this objective by placing considerable emphasis on model formulation and interpretation as well as on the techniques themselves, by generalizing theory from specific examples, and by providing non-mathematical descriptive information to help fix the principles.

After a short introduction on the nature of OR and the principles of modelling, the authors first try this approach with linear programming.

Starting with several practical examples on the formulation of LP problems, the the. The next chapter on network analysis deals in like manner with transportation, assignment and L.

DP is well-illustrated with a variety of examples to show its capabilities and limitations as a solution procedure. The authors, however, attempt to cover the whole of ion-linear programming in just one chapter in which the basic concepts, a range of search techniques, constrained optimization, quadratic, separable and geometric programming and the general non-linear programming problem are all constdered.

The subject matter of this chapter would be more suitable for a book on bptimization than on operations research, since the mathematical techniques mantioned Muthematical Programming for Management mtd Business, by G. Hayhurst, Edward Arnold, Since that time, operational research has expanded into a field widely used in industries ranging from petrochemicals to airlines, finance, logistics, and government, moving to a focus on the development of mathematical models that can be used to analyse and optimize complex systems, and has become an area of active academic and industrial research.

Others in the 18th and 19th centuries solved these types of problems with combinatorics. Charles Babbage 's research into the cost of transportation and sorting of mail led to England's universal "Penny Post" in , and studies into the dynamical behaviour of railway vehicles in defence of the GWR 's broad gauge. Harris in Operational research may have originated in the efforts of military planners during World War I convoy theory and Lanchester's laws.

Percy Bridgman brought operational research to bear on problems in physics in the s and would later attempt to extend these to the social sciences. Rowe conceived the idea as a means to analyse and improve the working of the UK's early warning radar system, Chain Home CH.

Initially, he analysed the operating of the radar equipment and its communication networks, expanding later to include the operating personnel's behaviour.

This revealed unappreciated limitations of the CH network and allowed remedial action to be taken. About operational research scientists worked for the British Army. Early in the war while working for the Royal Aircraft Establishment RAE he set up a team known as the "Circus" which helped to reduce the number of anti-aircraft artillery rounds needed to shoot down an enemy aircraft from an average of over 20, at the start of the Battle of Britain to 4, in Britain introduced the convoy system to reduce shipping losses, but while the principle of using warships to accompany merchant ships was generally accepted, it was unclear whether it was better for convoys to be small or large.

Convoys travel at the speed of the slowest member, so small convoys can travel faster.
