When managing complex systems, for example, an industrial enterprise, an organization, a socio-economic system, etc., it is necessary to take into account the fact that they can be considered as polystructural systems, i.e. as a set of heterogeneous systems, interconnected. A poly-structural system is understood to mean a variety of different components, differing in physical properties, functional purpose, complexity of the internal structure, representing a single whole. The article deals with the management of a polystructural system based on the preparation of management decision making by experts who can evaluate an alternative from the standpoint of a specialist of several elements of a polystructural system. To develop methods for determining and selecting an informed management solution, a polystructural system is considered from the standpoint of system theory and system analysis. A mathematical model is developed, which is the basis for creating information and algorithmic support for the management of the polystructural system.
Keywords: management of a polystructural system, the choice of an administrative decision, indicators, a problem situation, the method of analyzing hierarchies, reducing the complexity of the examination
The paper underlines the need for use of composite and nano-materials in place of natural materials, which is explained by depletion of global resources and increasing environmental pollution. This is why the focus is currently shifting toward the use of a composite material – porous artificial wood (PID-IV) – developed by the Irkutsk State University for making framework systems required to strengthen rectangular structural elements of buildings and structures. The framework system in question has a deck made of PID-IV. Further, the structural test was carried out in line with the effective regulatory documents, and the use of the suggested framework system was substantiated.

The transverse vibrations of the beams of a constant cross section are taken into account, taking into account the damping. We consider random oscillations of a beam under the action of vector kinematic and dynamic effects. The examples show the influence of correlation coefficients on the standard deviations of the cross sections of a beam. The internal forces in the form of bending moments and transverse forces are determined. An example of an action of a random process with a latent periodicity is given
Keywords: Beam, damping, deflection, bending moment, shear force, random process, spectral matrix, correlation, vector, matrix, transfer function
The paper discusses various aspects of economic safety in the construction company. In work it is noted that the attention of scientists to the issues of financial security. In accordance with a systematic approach to financial security is a security subsystem of the enterprise. Noted that with the help of indicators of financial security can be judged not only on the state of the financial system of the company, but also on the state of the other components of economic security of the enterprise as a whole. The scheme of determining the financial stability of the company
Keywords: management of construction; financial stability, economic security

This article presents the results of tests of samples on the basis of equiatomic alloy with shape memory effect. The obtained system of dimensionless quantities that adequately describe the elastic-plastic deformation. It is established that the assessment of scale effects in modeling shockproof device-based alloy with shape memory effect leads to the technical ability of extrapolation of experimental results to other objects to generate the initial data of the mathematical model under the condition of similarity of characteristics of external loads.

Physical education at the present stage of world development of society takes the form of a social phenomenon, is to strengthen the role of sport in the lives of everyone. Variety of sports meets a wide range of specially adapted facilities. The problem of technical modernization, stadium reconstruction and development as a multi-functional sports facilities (IVS). Profitability maintained and advanced facilities can be improved by putting into practice the principles of design of architectural form and structural theoretical model of the spatial organization of the IVS.
Keywords: reconstruction of the stadium, technical modernization, multi-purpose sports facility, the principles of formation of architectural, structural theoretical model
The ability to change brightness contrast of images with the help of some graphic packages’ tool is studied. In parallel the influence of this tool on hue and saturation of forming the image pixels is investigated. It is shown that tool as a whole is of little use for brightness contrast informative control, because in a number of packages it cannot provide brightness contrast gain, in others - does not keep hue and in all - deforms a saturation that threatens with loss of the graphic information transferred by saturation contrasts. Corresponding artifacts are considered and discussed.
Keywords: nonlinear brightness control, brightness contrast, colour hue and saturation, graphic information integrity, artifacts

Permits is one of the factors influencing investment attractiveness of the project. The article presents problems as well as significant differences in the procedure of obtaining building permits in various regions of the Russian Federation. Displayed certain investments and time needed for a permit. In the study "Doing business" presents a comparative analysis of regulations of business activities. Graphically shows the ranking of cities, as well as the Russian Federation itself in terms of ease of obtaining construction permits. Shown to work to reduce the time and cost of administrative procedures in construction in Russia and its regions. The proposed methods simplify procedures for obtaining permits, as well as mechanisms for optimizing processes in the field of construction.

The development of the approach to multi-criteria robust optimization is presented in article by developing of a technological machines robust optimization method in a joint synthesis of a parameters and tolerances on them. The ability to search for optimal solutions is the advantage of the proposed method in the absence of functional dependencies for single quality parameters from the input parameters that have extreme character and in terms of the existence of intuitive perception about their best averages. A structural (functional) synthesis, a parametric synthesis and a synthesis of tolerances theories were used to develop a method. This article may be useful for researchers studying the problems of finding optimal solutions during the implementation stages of creating and implementing life cycle of technological machines and for researchers studying the problems of improving the quality and competitiveness of technological equipment in domestic enterprises.
