ESTIMATION OF THE UNIT TORSIONAL RIGIDITY OF A CROSS-SECTION WITH A HYBRID DISK-EQUILATERAL POLYGON SHAPE

The economic sanctions of the United States, Canada, Australia, the EU in banking and technological sectors jeopardized Russia's national security. Moreover, the break of traditional technological chains of industrial enterprises in Russia and Ukraine set the task of accelerated import substitution. The economic situation inside the country is depressed, since internal reserves are insufficient for quick solution of the import substitution problem. An important condition to increase the efficiency of industrial production is the search for internal reserves at the local level, as well as ensuring sustainable operation of enterprises. The concept of sustainable operation of an enterprise includes its economic security, determined both by internal and external factors. In this paper a number of specific features of industrial production such as strict regulation and control by the state, a high level of specialization, technical complexity, the need for highly qualified specialists, and complexity of spatial placement is defined. Features of industrial production determine threats to the enterprise economic security. A high degree of regulation and control by the state creates the following threats: pressure of public authorities in order to obtain benefits, use of administrative resources in trade wars and raidership, frequent and drastic changes of laws, the risk of falling into dependence on officials, shareholders and partners. The focused narrow specialization of production negatively affects the ability of an enterprise to react quickly to market changes, and, first of all, the market conjuncture. This feature forms the following threats: falling demand for manufactured products, stiffening competition in a certain territory, aggravation of competition with enterprises producing similar goods, monopolization of the market, unfair competition. Due to technical complexity of the production process, the following threats arise: high degree of wear and tear of equipment, industrial injuries and manufacturing defects. A significant need for highly qualified specialists is conditioned by the complexity of the technological process and forms the following threats: labour shortage, low personnel qualifications, flow of highly qualified specialists to competitors, and the risky investments in personnel. The location of a number of industrial productions is bound to the locations of resources and markets. Metallurgical production is heavily dependent on the location of deposits of iron ore and coal. A number of industries gravitates to the market channels. Relationship of business owners and local authorities also influences enterprise location. Depending on the form of relationship, the enterprise is provided with the most comfortable or complicated business conditions. The considered specific features of ensuring economic security of industrial enterprises determined the arising threats. If security threats are known, they can be quantified, which will facilitate continuous monitoring of the situation. The program for ensuring economic security of an industrial enterprise should include continuous monitoring, a set of measures to neutralize threats and tools to minimize losses.
