Data Processing Application
An Introduction to Linear Programming
Data Processing Application
PREFACE
The purpose of this manual is to describe linear
programming, to show what can be accomplished
with it, and to prepare the reader to make intelli-
gent use of a linear programming system on a com-
puter. The presentation covers the entire scope of
a linear programming application: problem formu-
lation, computer operations, interpretation of
results, and additional information that can be ob-
tained through the use of a complete linear pro-
gramming system for a computer. There is no
attempt at mathematical rigor. Some of the mathe-
matical techniques are presented briefly to indicate
what is involved in the computer solution of a
problem, but no mathematical background beyond
high school algebra is assumed.
The glossary, however, is intended as a
comprehensive list of technical terms associated
with the solving of linear programming problems,
rather than as a list of only those terms used in
this manual. Furthermore, the definitions are
written in a technical manner for the benefit of
those readers who are studying linear programming
on a deeper level than that of this introductory manual.

CHAPTER 1: CONCEPTS AND EXAMPLES
Linear programming is a mathematical technique These examples emphasize the importance of
for determining the optimum allocation of resources linear programming. When a large number of in-
