Economic-mathematical methods and modeling

Economic-mathematical methods are currently widely used and are an important direction in the improvement of the analysis of activity of economic entities and their subdivisions. This can be achieved by reducing the deadlines of the study, the deep characteristics of the factors, and by replacing complex calculations more simple. In addition, in the process are set and solved the multidimensional tasks that you can perform by traditional methods or manually impossible.

Mathematical methods of economic analysis require:

1) systemic approaches to the study of economic activities of enterprises and account for all interrelated directions in different areas of management organization;

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

3) improve the system of presenting information about the economic activities of the enterprise;

4) the availability of automated systems, responsible for the processing, storage and transmission of data required for application of methods;

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

The task can be formulated accordingly and solved using mathematical methods. Also widely available statistics. Its methods are used in the case where the analyzed values are changed in random order. Statistical methods help to solve tasks for which the required forecast.

The Application of mathematics to the economy due to increased efficiency of analysis of activity of the enterprise due to the fact that you use the extension of the studied factors and justification of decisions. Also, the choice of the best variants of resource use and identification of reserves to improve the efficiency of production labor.

Mathematical models can be divided into 4 groups:

1) the exact optimization;

2) close;

3) not accurate optimization;

4) close.

The Use of these methods for analysis of the company helps to get a clear idea about the studied object, to quantitatively describe and to characterize its external relations and internal structure. Economic-mathematical methods are primarily used in the simulation. The sample, which in the end is a model object of study. The subject of management creates its display characteristics, properties, relationships, structural and functional parameters of the object, etc.

Unfortunately, in economic-mathematical modeling, the situation may arise when the object under study has a complex structure. As a result, it is difficult to create a model that will cover all features of the system under study. An example is the economic entity as a whole.
