The impact of uncertainty on strengthening the economic security of enterprises of the unified energy system of Ukraine

The importance of studying the issue of processes of strengthening the economic security of enterprises was quite justified in view of the military situation in the country and the deterioration, in this regard, of the economic situation of enterprises. Conditions of uncertainty are normative for economic entities, but they acquired a new meaning and became basic for enterprises. The goal was to form a theoretical and methodological basis for the processes of strengthening the economic security of enterprises in the energy sector of Ukraine based on the theory of uncertainty. The work was based on an approach to separating the stages of the uncertainty assessment process, dividing the main products of enterprises into components and using the method of analysis of hierarchies (MAI). As a result of the analysis of a wide range of scientific literature, it was determined that within the framework of the methodology of economic security, it is customary to use the tools of the theory of riskology and the corresponding methods and models of management. This work revealed the theory and practice of economic security of energy enterprises through the concept of uncertainty theory. A classification by types of uncertainty and the conditions of its occurrence for enterprises of the Unified Energy System of Ukraine (UES-U) was highlighted, which helped to choose the necessary tool for analysis. The conclusions obtained are of important methodological importance for forecasts of the development of the Unified Energy System of Ukraine in general and with the minimum, if possible, level of uncertainty. This is possible if the modelling of the Unified Energy System of Ukraine began with components with a lower level of uncertainty, and then complemented the model with options for other remaining energy facilities, related (coordinated) with the options of the industries from the first group. The results obtained allow for a holistic forecasting of the development of the Unified Energy System of Ukraine, taking into account factors of economic security and minimising the impact of uncertainty
