In a modern market economy a manager for technical management of activities - economic prosperous must know optimization theory alongside other modern techniques such as computer science, analysis system etc. Problems optimization helps us to determine an optimum solution if it exists. We observe that the correct formulation optimization problems is important. Linear programming is used to determine the best of resources to achieve a minimum c ost or a maximum benefit. In this article are presented some economic models that lead to problems of linear programming. On the basis of solving these problems lies Simplex method. The first step in solving such problems is mathematical modeling, namely respect for the general form of mathematical model.
