Ontology engineering to support strategic decision-making in the energy sector

The article describes the concept of ontological engineering as one of the methods of knowledge formalization and modeling and possibilities of its use for the purpose of supporting decision-making in the energy sector. The ontological engineering performed for situational management problem, is proposed by the authors to support strategic decision-making on energy development, taking into account energy security requirements. The principles of situational management correspond to the general scheme of energy security problems research and strategic decision-making related to the assessment of the energy objects status and fuel and energy complex as a whole, as well as the choice of the main directions of their further functioning and development.The article presents a graphical view of the ontologies that reflect key concepts of situational management, including situational analysis and situational modeling, as well as the option of the situation ontology, considered from the point of view of the energy security problem study. A set of developed and presented ontologies allows to integrate quite different concepts of the studied applied area to the collection that we call ontological space of knowledge for further use in the development of software for research and decision support in the energy sector.
