The navy linear programming application

For years his work, including the development of linear programming, was largely unknown in the West.

This is hardly a matter of surprise when one considers that they both share many of the same objectives, techniques and application areas. Most of the O. During the next thirty or so years the pace of development of fundamentally new O.

However, there has been a rapid expansion in 1 the breadth of problem areas to which O. Today, operations research is a mature, well-developed field with a sophisticated array of techniques that are used routinely to solve problems in a wide range of application areas.

This chapter will provide an overview of O. A brief review of its historical origins is first provided. This is followed by a detailed discussion of the basic philosophy behind O. Broadly speaking, an O.

The emphasis of this chapter is on the first and third steps. The second step typically involves specific methodologies or techniques, which could be quite sophisticated and require significant mathematical development.

Several important methods are overviewed elsewhere in this handbook. The reader who has an interest in learning more about these topics is referred to one of the many excellent texts on O.

The impetus for its origin was the development of radar defense systems for the Royal Air Force, and the first recorded use of the term Operations Research is attributed to a British Air Ministry official named A.

Rowe who constituted teams to do "operational researches" on the communication system and the control room at a British radar station. The studies had to do with improving the operational efficiency of systems an objective which is still one of the cornerstones of modern O.

This new approach of picking an "operational" system and conducting "research" on how to make it run more efficiently soon started to expand into other arenas of the war.

Perhaps the most famous of the groups involved in this effort was the one led by a physicist named P.

Blackett which included physiologists, mathematicians, astrophysicists, and even a surveyor. This multifunctional team focus of an operations research project group is one that has carried forward to this day. Its first presence in the U.

Like Blackett in Britain, Morse is widely regarded as the "father" of O. These ranged from short-term problems such as scheduling and inventory control to long-term problems such as strategic planning and resource allocation.

George Dantzig, who in developed the simplex algorithm for Linear Programming LPprovided the single most important impetus for this growth. To this day, LP remains one of the most widely used of all O. The second major impetus for the growth of O.

The simplex method was implemented on a computer for the first time inand by such implementations could solve problems with about constraints. Today, implementations on powerful workstations can routinely solve problems with hundreds of thousands of variables and constraints. Moreover, the large volumes of data required for such problems can be stored and manipulated very efficiently.

Once the simplex method had been invented and used, the development of other methods followed at a rapid pace. The next twenty years witnessed the development of most of the O.

The scientists who developed these methods came from many fields, most notably mathematics, engineering and economics.

It is interesting that the theoretical bases for many of these techniques had been known for years, e. However, the period from to was when these were formally unified into what is considered the standard toolkit for an operations research analyst and successfully applied to problems of industrial significance.

The following section describes the approach taken by operations research in order to solve problems and explores how all of these methodologies fit into the O.

A common misconception held by many is that O. While it is true that it uses a variety of mathematical techniques, operations research has a much broader scope.

It is in fact a systematic approach to solving problems, which uses one or more analytical tools in the process of analysis. Perhaps the single biggest problem with O. This is an unfortunate consequence of the fact that the name that A.

Rowe is credited with first assigning to the field was somehow never altered to something that is more indicative of the things that O. Compounding this issue is the fact that there is no clear consensus on a formal definition for O.In this paper we have proposed a vendor selection model using Integer Linear Programming (ILP) Model for multiproduct, multi-vendor environment.

The contribution of this research lies in the implementation of this model as a customized decision support system according to . CHAPTER 3 Applications of Linear and Integer Programming Models The Evolution of Linear Programming Models in Business and Government Following World War II, the U.S.

Linear programming is the process of taking various linear inequalities relating to some situation, and finding the "best" value obtainable under those conditions. A typical example would be taking the limitations of materials and labor, and then determining the "best" production levels for maximal profits under those conditions.
