1. Computational Modeling and Optimization
    Computational technologies were developed for computer modeling of the dynamics of complex systems in fluids with a free interface separating media of different densities. A comprehensive set of scientific and applied problems in the field of distributed systems dynamics was solved. The developed methods and algorithms are intended for use in computer-based forecasting and control systems for fast transient processes in real time (Acad. of NAS of Ukraine S.O. Dovhyi, Yu.I. Kaliukh, D.I. Chernii, O.H. Lebid).
  2. Theory and Methods of System Analysis
    A methodology for information and analytical support for assessing the state and forecasting the capabilities required to respond to threats in crisis situations and at various levels of national security management under conditions of incomplete and/or unreliable information was developed. Results were obtained to improve the effectiveness of managerial decision-making based on a methodology for developing probable defense-related scenario forecasts, preceded by a methodology for data collection, processing, and analysis to assess the available economic potential (Corr. Member of NAS of Ukraine O.M. Trofymchuk, O.M. Terentiev, T.I. Prosiankina-Zharova).
  3. Theory and Methods of System Analysis
    Information technologies were developed to support decision-making in regional development management within a distributed information environment under conditions of uncertainty and risk. Results were achieved in increasing responsiveness to risks and threats and improving the effectiveness of managerial decisions through the systematic use of mathematical models, data mining methods, artificial intelligence, a multi-model approach, and multi-criteria selection of development scenarios and decision options. The results have been implemented in the work of public authorities, local self-government bodies, enterprises, and in the educational process. A doctoral dissertation was defended (Corr. Member of NAS of Ukraine O.M. Trofymchuk, O.M. Terentiev, T.I. Prosiankina-Zharova, V.O. Vasianin).
  4. Information and Telecommunication Technologies
    The Institute developed an information technology for aerospace and geoinformation monitoring of marine areas and coastal zones. Results were obtained in enhancing the timeliness and reliability of environmental state assessments of the marine environment based on satellite data processing, artificial intelligence methods, and geoinformation modeling (Corr. Member of NAS of Ukraine O.M. Trofymchuk, O.H. Lebid, V.M. Trysniuk, Ye.O. Yakovliev).
  5. Information and Telecommunication Technologies
    An information technology and a hardware–software complex were developed for intelligent monitoring of radio communication networks under complex and dynamic electromagnetic environments. Results were obtained in improving the efficiency and substantiation of frequency resource management, detecting radio emission sources, and assessing communication channel resilience based on cognitive signal processing methods, deep machine learning, adaptive spectral filtering, and software-defined radio (SDR) technologies, using data from mathematical modeling and experimental studies (Corr. Member of NAS of Ukraine O.M. Trofymchuk, V.M. Trysniuk).
  6. Cybersecurity and Information Security
    A post-quantum non-commutative cryptography key exchange protocol was created on a platform of polynomial transformations over a finite space, enabling generation of a word of length n in a binary alphabet in time O(n²) (V.O. Ustymenko).
  7. Information Technologies and Artificial Intelligence Systems
    A new method was developed for calculating the empirical hydraulic resistance coefficient, known as the Chezy roughness coefficient, using an ensemble modeling approach with artificial neural networks based on field data on hydro-morphological parameters of open river channels (D.V. Stefanyshyn, Ya.V. Khodnievych).
