Economic-mathematical methods and modeling

Economic and mathematical methods are now widely used and are an important direction in improving the analysis of the activities of economic entities, as well as their units. This can be achieved by reducing the timing of the research, a deep characterization of factors, and by replacing complex calculations with simpler ones. In addition, multidimensional tasks are set and solved in the process, which can not be performed by traditional methods or manually.

Mathematical methods of economic analysis require:

1) the systematic approach in the study of the economic activities of enterprises, as well as accounting for all interrelated areas in various areas of the organization's management;

2) develop a set of economic and mathematical models that reflect the characteristics of the tasks and processes set in quantitative terms;

3) improve the system of information on the economic activities of the enterprise;

4) the availability of automated systems that are responsible for the processing, storage and transfer of data necessary for the application of methods;

5) the organization of specially trained personnel, which will consist of mathematicians, programmers , economists, operators, etc.

The task can be formulated appropriately and solved using economic and mathematical methods. Also, statistics are widespread. Its methods are used in the case when the analyzed indicators change in a random order. Statistical methods help to solve problems for which a forecast is needed.

The application of mathematics in the economy is due to the increased effectiveness of the analysis of the enterprise's operations due to the fact that the expansion of the factors studied and the justification of the decisions taken are used. Also, there is a choice of the best options for using resources and identifying reserves for increasing the productivity of production and generating labor.

Economic and mathematical methods can be divided into 4 groups:

1) precise optimization;

2) approximate;

3) exact not optimizing;

4) Approximate.

Application of these methods to analyze the activities of the enterprise helps to obtain a clear idea of the object under study, quantify and characterize its external links and internal structure. Economic and mathematical methods are used primarily in modeling. The sample, which as a result is obtained, is a model of the object of investigation. The control entity creates it with a mapping of characteristics: properties, relationships, structural and functional parameters of the object, etc.

Unfortunately, in economic and mathematical modeling, a situation may arise where the object under study has a complex structure. As a consequence, it is difficult to create a sample that will cover all the features of the system under investigation. An example is the economy of the economic entity as a whole.
