The atomic structure of bimetallic nanoparticles of Pt-Ag composition, which are the part of metal-carbon electro-catalysts PtAg/C, is studied by means of EXAFS spectroscopy using the suggested technique. These materials have been prepared by methods of consistent and simultaneous deposition of Ag and Pt atoms from aqueous ethylene glycol solutions of their salts with subsequent acid treatment. The values ​​of the structural parameters of the near environment of platinum atoms are determined. The nature of the distribution of components in nanoparticles is established. Cluster models of nanoparticles are constructed. The fraction of Pt atoms in the working shell and its dependance on preparation methods in each case are determined.

As a rule, the information they have guides for fatigue testing geometrical designs, gives only the evaluation of the characteristics and design lay stock in several, and sometimes in tens times exceeds the tensile strength of the material. And saving of material, from the point of view of obsolescence, product should be developed on a certain resource. For details, which operate in the field of elastic deformations and calculated in operation for a given mode of operation should lay in the design of the guaranteed resource. To do this, for example, compensating coupling method is suggested, which is based on the calculation methods of CAD/CAM/CAE/CSE NX 7.5 and field tests considering the impact of technology of surface hardening. The character of strain in «elastic element» in NX 7.5. The calculations of the elastic element module «flexible body» NX 7.5, but due to the fact that the calculation is impossible to consider technological parameters of manufac-turing is conducted equivalent full-scale tests. Accordingly, designed and built a stand for equiva-lent tests. Finally, for comparison, is a computer simulation to calculate large displacements and complicated movements of the coupling. For this we used the application NX 7.5 «Simulation of kinematic mechanisms» with the attraction tools «Flexible body».

To date, questions the reliability and continuity of electrical energy production facilities are among the most urgent , due to the transition generation companies into private hands and aggravate financial, economic and industrial- technological challenges : depreciation and obsolescence of equipment, lack of investment and other factors, influencing the power producers .
The article discusses the various valuation techniques of industrial enterprises and industrial complexes electricity . On the basis of their proposed universal method of estimating production complexes electricity , which is divided into 6 groups and includes weights . The article noted that the proposed method of estimating the weight of electric power systems operation has several advantages compared with the methods of other authors.

This article is devoted to description of structure of methodology of modelling of hierarchical problem-directed systems on the example of social and economic systems. In the basis of methodology the principle of a combination of the formalized methods of modelling and expert procedures is put. Modelling of hierarchical system is offered to be spent by means of multilayered fuzzy cognitive maps. Filling of the block of logical-mathematical models in structure of process of decision-making is described in detail. The offered methodology provides the development and choice of well-founded administrative decisions.

Keywords: Problem-directed system, decision making, fuzzy cognitive model, methodology

The article is devoted to modelling of process of decision-making in difficult systems in the conditions of total uncertainty. The problem is formulated on the basis of synthesis of concepts of the control theory and decision-making, the theory of fuzzy sets and the fuzzy logic, the theory of hierarchical multilevel systems, the utility theory and the theory of games. The given concept expands possibilities of the account uncertainty the various nature, typical to mathematical description of the surrounding validity. Problems of search of decisions in an fuzzy hierarchical control system are designated. The way of the description and finding of alternative decisions in multilevel difficult systems is offered in given article. The algorithm is based on information processing in the form of fuzzy intervals taking into account two kinds the politician conservative and aggressive on the basis of criteria «maxmin» and «minmax». The method of projection on individual interval is used for comparison of the fuzzy intervals presented on various dimension scales. The example showing work of algorithm of a choice of two groups of alternatives is resulted: optimistic and pessimistic on a level of hierarchies of the purposes in the conditions of total uncertainty.

This paper proposes criteria for the optimal choice of a database management system (DBMS), based on the requirements to this system. Empirically assessed criteria and method of analytic hierarchy process for decision making were used to carry out the comparative analysis of several DBMSs, implementing relation data model and having similar functionalities. The obtained matrixes of pair-wise comparison are examined for concurrence by calculating indices described in the article. As a result, the database management system for the own project is rationally chosen.
