- Yatsalo B., Gritsyuk S., Mirzeabasov O., Vasilevskaya V. The new approach to uncertainty treatment within multicriteria decision analysis taking into account uncertainties of criteria values and subjective judgments has been presented. The methods suggested (FMAA, Fuzzy Multicriteria Acceptability Analysis, and ProMAA, Probabilistic MAA) are based on assessing rank acceptability indices. The general approach to FMAA/ProMAA implementation along with its specification for multicriteria additive utility models is discussed. Realization of FMAA/ProMAA/is based on the numerical approximation of functions of random/fuzzy variables and the numerical assessment of integrals without Monte Carlo simulations. The decision support system DECERNS WebSDSS which implements FMAA and ProMAA as well as several other multicriteria decision analysis methods has been briefly described.

- Andrienko A., Tropova E. The method is offered to construct estimates of spectral density of a stationary process on the basis of its realization of limited duration. Increase of accuracy of these estimates is achieved by the variation of the width of the spectral window in the function of supervision time and of the local characteristics of spectral density.

- Solnechnyi E., Cheryomushkina L. For a special sort of boundary conditions of stable one-dimensional finite-length object of heat conductivity estimates are derived of norms of the operators translating boundary influences into the object temperature. These estimates are used for finding a sufficient condition of causality and stability for the system consisting of the object and the nonlinear feedback.

- Algazin G., Algazina J. The management problem is considered for a "manufacturer-mediator-market" system. The model accounts for asymmetric information and limited rationality of economic agents. Cournot and Stackelberg equilibria are calculated and analyzed. The relation is studied between the profit of a manufacturing firm and the size of its distribution network in a competitive market. Applications include agents’ interactions organization and distribution network optimization.

- Gurman V., Matveev G., Trushkova E. A general procedure of the approximate optimal control synthesis for socio-ecological-economic model of the region is developed. A set of programs DSEEmodel 1.0, which implements at the cluster computing devices parallel algorithms for scenario calculations, optimization and improvement of an approximate optimal control for socio-ecological-economic model to conduct multivariant calculations relating to the development of strategies for sustainable development in the region is created. In general, this is a new approach to the problem of situational control region by using supercomputers to implement full-scale socio-ecological-economic model.

- Zhulanov E. We propose the mechanism of leveraging social and economic asymmetry of regions of Russia, which creates prerequisites for development of competition and growth of the economy of the country. Optimal resource distribution in economy is calculated from the linear programming problem. Decrease of asymmetry and increase of economy performance is achieved by the differentiation of tax rates. This differentiation must reduce disproportions in social and economic development and resources’ provision of Russian Federation regions.

- Anshakov G., Mostovoi J. We consider safety-critical complex systems consisting of a large number of mechanical and electronic subsystems to be controlled and coordinated. Safe control in such complex technical systems (CTS) is based on the capabilities of the built-in computing machinery to monitor states of the subsystems and the ÑTS as a whole and to make control actions in contingency situations. The problems of safe control in ÑTS are considered on the basis of authors’ experience of on-board complexes control systems development for space vehicles.

- Maikov I., Director L., Zaitchenko V. The method is suggested to solve one of the most important problems in the field of effective heat supply both in the case of the strong hydraulic deregulation of a heating system (a static problem) and in the case of varying thermal loadings (a dynamic problem). The numerical procedure is developed for heating system analysis and optimization, which allows solving heat-consumption regime optimization and control problems for considerably large heat networks. Both static and dynamic problems are shown to reduce to a single general nonlinear optimization problem. The optimization algorithm is built where goal function minimization is carried out in an iterative process using the method of coordinate-wise descent.

- Melent’ev V. One of essential issues in computer systems (CS) control is limited decision-making time. Timing of control actions in the process of computer system functioning is in many respects determined by compactness of its structure providing the minimal number of transits at realization of intermodule communications. Compact structures ÑS are defined as regular graphs of an order n with the minimum diameter. These graphs are compared with (s, g)-cage graphs. The method of compact graphs synthesis is suggested. The method is based on the representation of compact graphs by the set of vertex-complete projections with minimally possible number of levels. Examples of n(s)-compact graphs built are given.
