Abstract of the direction
Founder and Head of the Direction – Doctor of Technical Sciences, Professor Oleksandr Serhiiovych Kutsenko
The relevance of this direction is driven by the geographical and geopolitical conditions in Ukraine, which lacks sufficient energy resources. The structure of energy consumption is significantly influenced by the extended heating season. Approximately 30% of fuel and energy resources are directed toward residential and municipal needs. At the same time, the efficiency of energy usage is 4–6 times lower than in countries with similar climatic conditions.
Thus, scientific and technical research in the field of optimizing heat supply control processes based on the criteria of comfort and energy efficiency is highly relevant.
This direction exemplifies a systematic approach to a complex scientific, technical, and economic problem. The research employs a wide range of scientific approaches, methods, and disciplines, including:
- Mathematical modeling of complex systems composed of numerous diverse elements described by ordinary differential equations and partial differential equations;
- Synthesis of heat supply control systems under the uncertainty of weather conditions and parameters of the thermal carrier generated by boiler installations, as well as varying consumer demands;
- Systematic organization of interactions among heat supply process participants at both national and regional levels, and more.
Obtained results
The Department of System analysis and information-analytical technologies (SAIT) has been working in the field of improving heat supply process control systems for nearly 10 years.
Within this research direction, one PhD thesis has been successfully defended, and another dissertation for the Doctor of Philosophy degree is currently prepared for defense. Eight master’s qualification theses have been completed. More than 25 scientific papers have been published in professional Ukrainian journals and international conference proceedings, 5 of which are indexed in the Scopus scientometric database.
