There are many ways to improve the decisionmaking
process, but, with a big amount of data and
complexity of decision-making trees, it's becoming
more and more complicated to keep up with the flow
of information coming from many spheres of modern
life. Therefore, the development of various problemsolving
approaches has become an important step in
changing the face of existing technological systems.
This idea appeared in the work of an American scientist
J. Perl who, in 1988, founded a new probabilistic
approach to artificial intelligence and developed
principles of Bayesian Network. Bayesian Network is
a graphical model that represents a set of random
variables and their conditional dependencies. In the
article, the most valuable parts of the given topic
have been reviewed, cognitive maps have been compared
with their partial manifestation - Bayesian
Network; also, one of the options to practically use
such models in the audit field has been analyzed by
observing a possible decision-making process of giving
a modified or unmodified opinion
In this article we justify the position about automation of the economic account of region. The model of the economic development of the region is designed in the article, under different variant of the management decisions on municipal level. It is intended for analysis of the spending the budgetary funds, using production and labor resource, introduction leading technology and condition of the developing branches
Mathematical modeling is one of the leading places among methods of research of economic systems and processes. The article considers the main management problem of the rocket-space complex in modern conditions and gives a brief description of this problem in conjunction with the tasks of innovative modernization and financial sustainability of enterprises of the complex. We have considered a common situation where the enterprises of the rocket-space complex in implementation of its development is carrying out an investment project, the financing of which is taken from a loan. It is proved that the implementation of this project can be appropriate, if as a result of the implementation the net present value of the enterprise increases. We have developed a model, which provides optimization of financial providing of high-tech enterprises of the rocket-space complex in the implementation of their modernization project taking into account the specifics of the use of own and borrowed funds
The global financial crisis has had a negative impact on the domestic economy, resulting in a much more complicated task of achieving the most important indicators specified in the Concept of long-term socio-economic development of the Russian Federation until 2020. Implementation of the goals depends on a number of factors, including, how successful energy efficiency policy in Russia will be implemented.
In this regard, actual task is to analyze the impact of the energy factor on the dynamics of change of gross domestic product in Russia
Production and processing of grains formed in the national economic system of the country a number of cereals-governmental sectors, such as grain production, grain elevator industry, flour, cereals and mixed fodder production, which constitute the grain complex country. The significance and role of the grain as a commodity in the state economy can not be overestimated. This product is totally liquid, which has a constant, steady demand at any time of the year, in any region. Ongoing measures to increase grain production and improve its implementation did not have a complex character, therefore, insignificant effect on the efficiency of the industry and the competitiveness of grain production. The shortage was covered by imports. According to the characteristics of management in agriculture, it should be emphasized that the absence of objective and timely information at all stages of production of the plant-breeding, and as a result, non-optimal choice of technology of cultivation of agricultural crops, might result in the fact that the cost of labor and material resources increases significantly, the company does not receive profits, and sometimes suffers losses. When selecting cultivation technology for agricultural crops, an agronomist has a database of more than a hundred times-personal of alternative technologies for each crop. It is up to the decision-maker (DMP) to find specific criteria to select the most suitable (for the owners and the climatic zone) technology of cultivating for the culture. These circumstances explain the relevance of in-depth research of economic and mathematical models and methods of analysis and evaluation of the economic efficiency of technologies of cultivation agricultural crops. The article deals with the process of developing a complex of mathematical models and methods for evaluating alternative technologies for agricultural production (using the example of crop production), their software implementation, and the main scientific results of the project
Plant growing successes influence the effectiveness not only the branch in itself, but the other branches
of agriculture, economics of agricultural enterprises
in whole as well. Models and methods of decision taking process improvement in plant growing were considered in the paper.
The analysis of activity of a sugar subcomplex has allowed to develop the specified schemes of re-structuring of the integrated industrial systems of the sugar subcomplex, the concept of interaction of objects of the integrated industrial systems of the sugar subcomplex, its information, monetary and material streams, and also to construct structure of the purposes and functions of a control system of the integrated industrial systems of the sugar subcomplex. The complex of mathematical models of costs estimation of using ground resources of the integrated industrial systems of the sugar subcomplex, the system of mathematical models of efficiency management of the integrated industrial systems of the sugar subcomplex and a quantitative technique of an estimation of activity of the integrated industrial systems of the sugar subcomplex are developed.
Models of improvement and assessment
of organizational structures of management system
of regional consumer cooperation are considered in
the article. Method of organizational structures improvement, which allows using instrumental means of systemic, cognitive analysis, theory of mass service, to work out organizational structures with an account of changes of external environment and to assess offered variants by criteria of information transmission
speed was offered.
Complex of models for management of
production effectiveness in farms for mono product, multi product and mono processing types was proposed in the article.
In the article the review of existing models of management is given by a specialty store chain. The basic differences of the Russian and foreign approach to a choice of the system integrator are discussed. Influence of a financial crisis of 2008 on activity of commercial companies is analyzed.
