Head Trofymchuk Oleksandr M., д.т.н. Registration Date 14-05-2025 Organization Institute of telecommunications and global information space of National Academy of Sciences of Ukraine popup.description1 The main goal of the work is the creation of new mathematical models, methods, and information and communication technologies to improve the quality of decision-making in the management of critical infrastructure, ensuring its protection, stability in conditions of uncertainty caused by the action of various factors and threats. popup.description2  As a result of the research, methods of intelligent data analysis, mathematical models, methods, theoretical and methodological foundations of modeling were proposed for modeling and forecasting vulnerabilities of critical infrastructure, identifying the largest and typical threats, in particular, cyber threats, an interdisciplinary forecasting toolkit was implemented both to determine the probability of a critical situation and the consequences of the impact of various threats and factors on the development of events under different scenarios, systematic use of methods that solve predictive modeling tasks within the framework of weakly structured tasks of decision-making support in managing the cybersecurity of critical infrastructure objects in a situation of threat or risk. To ensure cyber protection of critical infrastructure objects, a cryptosystem was developed based on non-commutative methods of computer algebra and the theory of symbolic computation. To solve the problems of optimizing flow management in hierarchical information and communication networks with discrete flows, mathematical models, methods and algorithms have been developed that can be applied in transport and military logistics systems. The proposed models, methods and algorithms are intended for use in the proposed information technology, which involves the processing of real processes taking place in the country's critical infrastructure, in order to ensure their stability, an appropriate management solution is developed. The peculiarity of the proposed methods is that they are universal; in the process of developing models, the research is carried out in several stages, gradually changing the level of detail, simulating the behavior of the system, identifying new development problems and external and internal factors that cause them. The peculiarity of the proposed approach is the expansion of the tools of mathematical modeling and decision-making support through the use of ensembles of m Product Description popup.authors Bidiuk Petro I.
