Fuzzy logic in the evaluation of investment attractiveness innovation projectsThis paper proposes a new approach to the evaluation of investment attractiveness of innovative projects in the linguistic uncertainty caused by the nature of qualitative criteria to be applied. The authors propose an economic and mathematical model that supports decision-making about the level of investment attractiveness of the project that is based on the use of the mathematical apparatus of the theory of fuzzy algebra and implemented with specialized package Fuzzy Logic Toolbox in the system MATLAB. The advantage of using this model is the ability to formally describe the knowledge of experts and professionals in selecting strategic guiding economic and production structures, in addition to evaluating the economic benefits of the project semi-structured assessment of social utility and environmental safety.безопасности.

Budget management based on fuzzy algebraThe problems of modeling tools create a decision support system for management of the budget for computer processing characteristics of the budget, expressed in the form of logical structures of natural language and representation of linguistic variables. Automaton constructed economic and mathematical models to solve the problem of generation of chains, which give qualitative assessment of the revenues and expenditures, as well as their recognition in a given formal grammar.

Logical-dynamic model of decision support on interbudgetary regulation
The article is devoted to creation of IT-based tools in economic-mathematical models of management
of the interbudgetary regulation in the structure region — municipality. The object of control is
a budgetary Fund of the municipality. The complexity of behavior occurs due to the presence of many
modes of operation of the control object caused by a change in the structure of revenues in municipal
budgets at the expense of use of means of budgetary regulation. In this case, financial assistance can
be replaced by deductions to local budgets from federal and regional taxes on the norms that are set at
the regional level. The existence of various modes of operation is due to a change in the list of taxes,
part of the proceeds from which are transferred to the municipality according to established standards,
which are taken for structural conditions. To formalize the formulation of the problem of managing
interbudgetary regulation, the article proposes the principle of coordinate-structural control, which allows
one to take into account the variations of discrete structural states. A conceptual model of management
of interbudgetary regulation in the form of a complex of interacting dynamic systems is proposed:
continuous and discrete. A continuous dynamic system realizes control in the continual region
of the finite-dimensional space of income and expenditure and is constructed in a class of simulation
models. To formalize the functioning of a discrete dynamical system, a model of a stochastic automaton
functioning in random environments has been developed. The article proposes the structure of a
stochastic automaton with selective tactics. Formal expressions are obtained for the final probabilities
of an automaton in each of its states. The automaton of the proposed structure has the property of expediency
of behavior and asymptotic optimality in the choice of the norms for the distribution of taxes
between the levels of the budget system. The article presents the results of the software implementation
of the simulation model. The use of model tools in practice will make it possible to increase the degree
of validity of decisions taken on interbudgetary regulation by means of their quantitative assessment.

Instruments and institutions of the information economy in the industrial development of RussiaThe paper reveals the essence, features, and characteristics of the information economy.
The tendencies toward transformation in the economic development within industrial enterprises
in the area of information and communication are demonstrated on the basis of this analysis.
The specific features of the current state of industrial development in Russia are shown and the
role of institutions in enabling innovative activity by enterprises in the real sector of the economy
is described. Tools are proposed for the information economy, permitting the elimination of
current limitations and enabling the functions of institutions of innovative industrial development
in the conditions of considerable regional variation. Particular attention is paid to the potential
for electronic government in the industrial development of the economy.

Model instrumentation of strategic management of industrial enterpriseThe article is devoted to solving the problem of improving the strategic management of industrial
enterprises in conditions of uncertainty created by fluctuations in the external and internal environment
conditioned by the current economic and political situation in the country, as well as market conditions.
The purpose of the article is to develop tools that support decision making when choosing strategic
guidelines for the development of enterprises using economic and mathematical methods. A study is
made of the system of strategic management of an industrial enterprise with the property of development
based on the application of the methodology of system analysis. The model of the process of strategic
management is developed in the form of a logical structure containing a joint solving procedure
for solving problems, starting with the study of the external environment and the development of the
mission, and ending with the creation of an economic and mathematical toolkit and its use to evaluate
decisions. Economic and mathematical tools have been built to support decision-making regarding the
strategic guidelines for the development of an industrial enterprise in conditions of stochastic uncertainty.
As a characteristic of the profitability of strategies chosen profitability. The toolkit is created in
a class of simulation models and allows to reproduce the dynamics of a company’s profit and capital
expenditures by the method of statistical tests, as well as to forecast on this basis the profitability of
various options for strategic orientations of the enterprise’s functioning. The constructed economicmathematical
models are algorithmized and implemented in a software product that allows the strategic
manager to scientifically and quantitatively substantiate the decisions made in the dialogue with
the computer. The article demonstrates the work of the software product in the course of simulation
experiments and their processing in assessing the selected strategic benchmark in terms of profitability.
The built model toolkit is intended for use in industrial enterprises to support strategic decisions.
