The efficient development of the national economy largely depends on the level of support for its economic security (ES) because an independent external and internal policy that meets national interests can be pursued only in this context. The purpose of the study is to analyze the features of managing the ES of a business entity in the context of financial instability (FI). The relevance of solving the problem of ES for entrepreneurship as a factor of the state's ES is revealed in the article; various theoretical approaches to understanding the essence of ES for entrepreneurship, as well as FI of a business entity as a threat to ES for entrepreneurship are analyzed. Expert opinions on priority models for assessing the financial condition of a business entity are generalized on the basis of an expert survey, and international experience in preventing bankruptcy of business entities is analyzed to compass the purpose.

This paper explores the essence and establishes the key characteristics of companies’ economic security in a climate of changing market conditions. Based on a summarization of research into the market conditions, the authors performed modeling of risk from changes in conditions in Russia’s petroleum machine-building market using the paired comparison method

The aim of the study is to simulate the probability of occurrence of economic risks in industrial enterprises using trees of logical possibilities, and the subsequent ability to manage them. To solve the set goal, the method of expert survey was used. The expert evaluation was carried out by the ranking method to determine the probability of occurrence of each of the economic risk components. The expert evaluation involved executives of industrial enterprises and managers of commercial banks. According to the research results, the risk assessment of an industrial enterprise should be focused on the study of the impact of primary economic risks. This can be done by building a tree of logical possibilities (usually called also logic tree) of occurrence of industrial, commercial, and financial risk components of the industrial enterprise. Visualization of the study using trees of logical possibilities along with conducted expert survey will help to establish quickly and clearly the levels of risk components and predict the state of the enterprise based on the actual circumstances.
