The article discusses the approach to the assessment of critical information infrastructure (CII), operating in cyberspace in conditions of information warfare. The result of assessment is the value of the integral criterion of ability to achieve goal function CII at each moment of time. The novelty of work is determined by the consideration of promising evaluation method of complex technical systems with a high degree of criticality and uncertainty representation. The practical significance consists in the fact that the new evaluation method can be used to improve the efficiency of management CII, and to justify new forms and methods of warfare in cyberspace. The article deals with the issues of cybernetic sustainability, its core components, and properties of management determining the cyber stability. Classification of CII objects is done. The formal definition of the cyber stability measure, the technique and the algorithm of its calculation are given.

The article is devoted to the integration of quantum key distribution systems and existing certified encryption systems. The structural scheme of the quantum communication system is considered, and a brief review of the experimental results on the implementation of quantum-protected data transmission in fiber-optic communication lines is presented.

The article describes the new mathematical model of the geological environment viscosity of the Earth lithosphere for its continental and oceanic parts. In the viscous models of the lithosphere are taken into account temperature, pressure, strength, density and other physical-chemical properties of the geological environment, changing with depth. The dependence of the activation energy from the lithosphere temperature is specified. New method for estimating coefficients of the model, taking into account empirical data on viscosity in some characteristic points of the lithosphere, is implemented. Based on the model in the depth range from 0 to 80 km with an interval of 1 km distributions of viscosity in the lithosphere found. The simulation results indicate a relation of viscosity with the earthquake zones near oceanic tectonic faults. Namely, in the zones of low values of viscosity at the depths of 33 km occurred at about 40% of all registered earthquakes. In the article new scientific results are obtained and important contribution to the solution of the task numerical estimates of the characteristics geodeformation processes has done. The obtained results help to better reflect real conditions of geological environment in the calculation of geodynamic deformations, and to predict the dynamics of modern geodeformation processes in the lithosphere.

The models of temperature calculation for continental and oceanic lithospheres directed to assessment of geodynamic threats are considered. The heat conductivity equation for the stationary mode of heat generation in geological environment, and the equation of cooling-down half-space and Taylor’s row decomposition of the error function are used.

Manipulative models of information influences in social networks are considered. Their descriptions in the system dynamics notation in the form of a flowchart and the corresponding system of differential equations are given. Model experiments with the application of advanced simulation platform Anylogic was carried out. Comparing agentbased and system-dynamic models showed high agreement with each other and with statistical data. Based on the cluster analysis using real statistical data was allocated typological groups in the sample villages of Russia, which differ in the average time spreading of information influences. System-dynamic models of information influences spreading in social networks have been successfully tested. In addition, the Gibbs’s postulate on statistical ensembles with respect to spreading of an idea in student’s environment was confirmed. The high consistency of simulation results with empirical data is shown (the coefficients of determination are not less than 90%). Models allow the forecasting of informational influences and informational counteractions, and to study various scenarios of their development.

The article examines the theoretical and applied aspects of the new approach to the management of tourist destinations. Namely, network-centric management model. The model is based on the use of modern information technologies and network organization of information exchange destinations with consumers of tourism services and marketing organizations. Networks are considered as “clusters” or aggregation structures consisting mainly of small and medium tourism enterprises. The principle of self-synchronization in a network-centric management of destinations considered. The concept of “tourism and recreation attractor” is introduced and justified. “Borrowing” strategy in the application of innovations diffusion and advanced tourism and recreational technologies mechanisms in tourism industry of Russia regions is justified. Multinetworking scheme innovative development of tourist and recreational areas including educational segment is proposed.

The article discusses the complexity of decisionmaking problems in the practice of urban planning. A conceptual and mathematical apparatus of modeling and optimization algorithm for constructing planning decisions is considered. Planning the territory development is considered as a linear problem of synthesis of the communication type network structure. The resources of network structure of urban planning based on their formal description are represented. A method for the quantitative assessment of the network structure resources is described. The step by step procedure for the practical implementation of the construction objects optimal placement is given.
