Problems of perception of information in training, science, critical situations in the context of cognitive technologies are considered. To consider semantics of subject domains when using cognitive technologies - one of problems of the digital environment. This problem is offered to be solved by attraction of specialized subject thesauruses. It is noted that during a digital era the role of specialized thesauruses as bases for ontology data presentation increases in information systems. On the basis of thesauruses it is easy to create ontology of a situation and to use it as model of data for cognitive agents.

Long-term forecasting of energy demand is the first and an important stage in the development of regional and national energy strategies and policies. Changes in the conditions of future energy development by spreading smart grid impose new requirements on the methodology of energy demand forecasting. Consumers are important component of the Smart Grid concept. In future consumers as equal energy market participants can form demand and prices and influence on level of energy system adaptability. Urgent task is to estimate the impact of consumer behavior on prospective electricity demand in a regional power system. The use of semantic approach allows us to overcome the difficulties in modeling the impact of consumer behavior that are associated with high uncertainty and impossibility to formalize grid-consumer interconnections. The developed algorithm and models based on the agent approach make it possible to assess the possibilities and the strength of consumer behavior effect on the structure and operating conditions of the regional power grid.

Intellectual decision support in the development of an industrial enterprise is based on knowledge management, aimed at improving business processes and ensuring the competitive advantages of an enterprise. In modern conditions of development of high technologies, the importance of personnel management, the corresponding long-term strategy for the development of the enterprise. This article discusses the tasks of personnel efficiency management, for solving which it is proposed to apply both mathematical optimization methods and artificial intelligence methods, such as data mining, ontological analysis and decision making using the knowledge base.

The article proposes a conceptual model of knowledge for the study of the fuel and energy complex as a critical infrastructure. A system of interrelated ontological models reflecting the basic concepts of the subject area and their relationship is proposeing as a conceptual model. The structure of the fuel and energy complex objects, the tasks of research from the standpoint of energy security, the models used for research and the corresponding information base are considered. Quantitative information is presented by technical and economic characteristics of energy facilities, reporting data and research results on the development of the fuel and energy complex. The developed system of ontologies is using to structure and integrate knowledge in the study of critical energy infrastructures.

The article describes the solution of the fundamental scientific problem, which consists in the development of methods and intelligent technologies for the scientific substantiation of strategic decisions on the digital transformation of energy, taking into account the requirements of cybersecurity, based on the concept of situational management, using methods of machine learning, evolutionary computing, mathematical and semantic modeling.

Metatheoretical (MT) bases of intertheoretical mathematical modeling of natural, economic and social systems are discussed. The main MT-statements are formulated in terms of differential geometry of tangent fibration and foliation on manifolds taking into account experience of creation of polysystem models in geographical science. The manifold is interpreted as the geographical environment of formation of the phenomena and processes. The equations for their modeling appear respectively as a result of mapping estimation functions upon vector fields of states and velocities of the fiber space. The tangent point of fiber contact is interpreted as environmental type of realization of the modelled regularities, and it’s global coordinates correspond to conditions of environmental shift of system parameters. Taking into account these shifts the local system of coordinates is formed. The created MT-equations of connections and changes of relative parameters don't depend on the choice of global (external) and local (internal) coordinate systems. The foliation of the environment manifolds defines topological and typological structures of a research space as geoinformation source of knowledge on heterogeneity of local conditions. MT-modeling proposes the universal equations and allows taking into account an originality of systems and their environment through content-related interpretation of abstract concepts and environmental shift of variables. For MT-modeling the structures and functions connected with fibers are of importance, in particular, trihedrons and tetrahedrons of lines and surfaces. Their analogs are formal categories as the commutative diagrams of connections of concepts generating laws of creation of any system models.

The continuous changes and development of electric power systems lead to their complication and enlargement. In this connection, existing models and software systems that allow to assessing the adequacy of such systems may work not effectively in terms of time, accuracy and adequacy of results. To obtain objective information, there was made analysis of a number of existing power shortage minimization models, while solving the problems of assessing the adequacy. The materials of this article reflect the results of model studies on the presence of physically incorrect distribution of power flows between nodes. The existing of bilateral flows and a number of optimal solutions has been proved. The current approach that taking into account the adequate distribution of power flows, also has been tested. As a solution to the problems described above, the additional constrains on overflows were proposed, as well as a two-stage method for optimizing the flow distribution, which ultimately solved all the problems found.

The paper presents a methodological approach to automated construction of integrated graphical environment for computer modeling of pipeline systems of various types. Automated construction of the integrated environment is performed using a computer model of the pipeline system and ontologies based on the Model Driven Engineering concept and reflection programming.

The active development of hardware and software of the internet of things devices, as well as the development of the service-oriented approach can be observed in today’s world of informational technologies. This article proposes to implement various devices of the internet of things as web-services with definition of theirs interactions using the distributed service compositions execution in heterogeneous environment software system, developed in ISDCT SB RAS. Presented approach was probated during automation of the office building management processes and is currently under constant development.

This paper is devoted to the problem of visualization of multiparameter tabular numerical data on the example of processing the results of the study of critical two-phase flow through a spherical particles bed. An overview of interactive and streaming methods for working with tabular data is presented. The task of automating the plotting of scatter diagrams with several rows is solved by means of the programs gnuplot, gawk, sort, and their combination using data pipes. Special attention is paid to minimizing the efforts of the researcher, spent on updating the diagrams when entering new data and changing the requirements for the design of diagrams.

Information and algorithmic support for solving the main tasks of geomonitoring and assessment of the geodynamic danger of the territory of the Republic of Tyva are presented. Based on seismic monitoring data in 2010-2017 the development of elements of the method of data analysis of complex geomonitoring of geodynamic fields for the assessment of the geological environment and the accuracy of the forecast of strong earthquakes.

The paper contains a proposal for a secure data transmission technology. This technology can be used to build various low-power wireless networks, for example, in smart home systems, industrial wireless sensor networks, communication networks of Smart Grids. The peculiarity of such networks is that the devices from which they consist do not have sufficient power to support execution of asymmetric crypto algorithms.
