| Summary: | The urgency of the work is determined, on the one hand, by the importance of energy security issues and its research, on the other - by the need to develop intelligent research tools and their integration with traditional mathematical models. The main aim of the study: improvement of two-level technology of researching energy security problems by integrating semantic models and expanding ontological space of knowledge on object domain by event ontologies. The methods used in the study: On the top (first) level of the previously proposed two-level technology of energy security problems research a qualitative analysis (express analysis) is performed using the methods and means of semantic (ontological, cognitive and event) simulation, on the lower (second) level a quantitative analysis is performed on the basis of numerical calculations using traditional software systems. Cognitive models are used to simulate the energy security threats, event model are used to simulate emergencies development in energy sector. Joint implementation of cognitive and event modeling allows obtaining more objective evaluation of the situation. The paper introduces the event ontologies used for transition from cognitive to event-driven models and considers application of Joiner-nets for analyzing and processing event models. The results: The authors have proposed the rules for generating events ontologies. The paper describes the algorithm for automated transition from cognitive maps to event-driven models based on ontology (using events ontologies) as one of the stages of improving two-level technology. The article introduces the developed ontologies, cognitive and event maps and event model using Joiner-nets built on their basis. |
