Introduction. Under globalization, the current international political and economic relations, the Russian Federation is changing to a new state policy in the field of system modernization of public procurement. Theoretical analysis. The development of predominantly market-based mechanisms of regulation, liberalization of the economy along with degradation of the regulatory role of state governance structures lead to increased risks in public procurement. Individual problems and contradictions in the system of public procurement are due to the lack of proper methodological apparatus to estimate the effect of risk. Methods. As a result of our optimization statement of the problem of selection of an executor of public orders, an algorithm and a system of mathematical models of choice of potential suppliers considering the collective evaluation of the risk category are proposed. A distinctive feature of the proposed method is the use of techniques to allow for maximum relations among the basic elements in a risky situation (alternatives, the probability of achieving the result desired, uncertainty, the possibility of deviation from the intended purpose). Results. The proposed approach makes the necessary prerequisites for the establishment of effective barriers for fraud and incompetent agents to enter the system of public procurement, both as suppliers and customers, through our selection mechanisms developed. Conclusion. The future direction of development of the methodology seems to justify the qualification requirements for suppliers, including the availability of necessary professional and technical qualifications, financial resources, equipment, labor and other material resources for the execution of contracts, work experience.

Introduction. Any enterprise’s functioning in a market economy entails internal and external risks. Reducing their impact or leveling ensures a long-term existence of the business. In this view, the subject of the study is relevant. Theoretical analysis. The theoretical and methodological basis of the study was the works of Russian and foreign researchers in the field of economic and financial security. During the critical study of scientific publications it was determined that the interpretation of the financial security of enterprises definition is considered in terms of several approaches: complex, resource, financial. It was also found during the study that threats to financial security have a direct impact on production, personnel, information, etc. Empirical analysis. The main methods of research were analysis and synthesis, as well as the method of generalizing indicators. In the course of the study, it was found that the analyzed enterprise uses only quantitative indicators for evaluation, which are unable to identify most threats to financial interests. As a result, an open list of qualitative indicators was proposed that could assess the level of financial security. Results. The construction of the financial security risk matrix allowed us to establish that the total cost of implementing all risks per year can reach 90 million rubles, which is about 9% of the property of the enterprise. Having assessed the risks of financial security, we recommended that the management of the enterprise should pay attention to the realization of the profits loss risks due to the unstable position of suppliers and contractors in the market or the termination of their activities.

Introduction. Modern Russian banking system is going through a difficult period of reform and global change. Status of the Russian banking system reflects the general state of the economy and the financial sector of the country and the world. It is characterized by low immunity to numerous, including systemic risk, low maneuverability in a high level of uncertainty. All these factors reduce the functional capacity of the Russian banking system as a whole. Theoretical analysis. Risk management – a process consisting of five steps: risk identification, assessment and analysis, decision making, maximizing the positive and minimizing the negative consequences, monitoring, promoting a culture of risk management in the company. Empirical analysis. The position of regional commercial banks in the Saratov region in a difficult economic situation, however, is complicated by the high risk of external and internal environment. For the development and expansion of possibilities of lending to small and medium-sized enterprises must be at the federal level to facilitate regional commercial banks to access credit refinancing. One of the concrete actions can be a reference to federal regulators to allow banks to hold assets in a regional repository. Results. Further updating of risk categories allowed to evaluate and present ranked critical risks that are typical for the activities of the regional commercial bank.

Introduction. Efficiency of investments is an important factor at the micro- and macroanalysis of economy, investment in venture capital depends on the development of firms, regions, States. Especially actual this problem for portfolio investment. The aim of this work is to develop a new minimax method for modeling the dynamics of risk of portfolio investment, which allows to assess the distribution of equity is a structural component of a financial portfolio.

Methods. Suggested new method for modeling and rationalizing the structure of equity investments using the minimax criterion. Drill through the decision of the investor as from the original portfolio preferences, specific risk assessments for each lower level in the hierarchy (topdown) and a calculation of expediency of inclusion in the portfolio of each asset of the lower level, with specific risk assessments (bottomup), which is consistent with the approaches of fundamental analysis of securities market. Provided step-by-step algorithm for grouping, clustering and data analysis along the branches of the hierarchy.

Results. Is developed the scheme the implementation of the model for a three-tier structure for complete binary decision tree. Is given the iterative computational algorithm and its implementation.

Conclusion. The recommendations can be applied to rationalize the funding of innovations that improve the quality of development of regions in the rehabilitation plan for selected executives of corporate sector.
