It's provided to use multiagent system's technologies and ontologies for solving problems, directly relating to analyses, diagnostic, evaluation and identification of situations, forecasting of outcomes, information fusion, coordination of unmanned aerial vehicle's group operation. An approach is suggested, which allows analysing the correctness of ontology and its completeness, searching for disturbances in semantic links, agreement of representations about the subject area and the semantics of objects described in terms of different ontologies during their merging. Issues of mapping the elements of the OWL and SWRL-languages to a knowledge base of a decision support system based on the first-order predicate logic are discussed. The key principles of implementing an effective inference algorithm on ontologies for different strategies of search reduction are described.

Purpose. Efficiency of regional resource management improvement based on self-organization and adaptation in multi-agent systems in conditions of uncertainty and dynamic environment. Methodology. The given research studies are based on using system analysis methods in order to choose the directions of modeling regional management processes; simulation modeling and theory of multi-agent systems for agent simulation model for regional resource management development. Findings. Analysis of regional development management features and existing approaches and methods of analysis and decision making in this field was carried out. A structure of simulation agent model for regional resource management was designed. Originality. Simulation agent model for regional resource management was developed, economical self-organization and collective adaptation of model elements with their own interests and decision making process were implemented, which allows flexible decentralized resource management planning in conditions of a dynamic environment. Practical value. The designed model represents methodological basis for creating management decision making tools, which provides development planning and effective regional resource usage.

The features of improving energy efficiency at a metallurgical enterprise based on portfolio management of energy-saving projects are considered. A simulation model of energy consumption at the metallurgical enterprise, which covers the entire metal products manufacture process, has been developed. The parameters, conduct, and visualization of simulation models of the main equipment such as an electric arc furnace and a ladle furnaces are described. With this software package's help, a comparison of the permissible values and the adjusting of the predicted consumption of active power by a metallurgical enterprise for each fixed point in time are carried out. The system calculates the operating mode regulation range of electric arc furnaces to ensure the continuity of steel casting during melting of a particular steel grade along the appropriate technological routes. The model likewise includes algorithms for transport equipment management that minimize disruptions in continuous casting machines' operation and simulate emergencies. The analysis of the results of energy consumption processes simulation at the metallurgical enterprise is carried out. As a result of modeling, it was possible to increase the productivity of a group of electric arc furnaces and ladle furnaces and reduce the maximum consumption of active power by the metallurgical enterprise. Experimental studies of energy consumption planning methods have been carried out based on real data on the metal products manufacture and electrical energy consumption by the production units of PJSC "Electrometallurgical plant "Dniprospetsstal". The use of the electrical energy consumption model allows in an integrated manner and responds to the dynamics of production processes to carry out further calculations of economic feasibility studies, analysis, and selection of options for the project's implementation of an energy-saving portfolio at the metallurgical enterprise.
