The reference book of the software package LINGO contains large numbers of alternative operations research models and applications with numerical solutions. Usually, in applied problems, there are many different ways to define the mathematical models representing the components of the system under analysis. Chiang, A.C., Fundamental Methods of Mathematical Economics, McGraw-Hill, Inc., 2 ed., 1974ġ2 Mathematical modeling is central to operations research. The classical analytical methods of optimization and comparative statics analysis, basic economic theory and fundamental linear programming are well presented in Chiang. In this paper, we will focus on operations research in connection to optimization of decisions, with one or more decision maker(s). Keywords: Operations Research, Mathematical Modeling, Optimization.ģ Introductory examples of important real world decision problems that can be developed to applications of operations researchġ0 Introduction to mathematical modeling and operations researchġ1 Operations research is a very large area.

The discussed methods and examples are motivated from the points of view of empirical relevance and computability. This paper presents fundamental and general decision and information structures, theories and examples that can be expanded and modified in several directions. The numbers of alternative models, methods and applications of operations research are very large.

Theoretical understanding of the relevant problem structure and consistent mathematical modeling are necessary keys to formulating operations research models to be used for optimization of decisions in real applications.
