The stochastic model of an assessment of mechanical characteristics of strength on the basis of the analysis of function of reliability is offered. Communication of function of reliability with normative factor of safety factor is correlated. Recommendations to destination mechanical characteristics of strength on Gauss to a level and factors of a variation are given. Analytical and graphic dependence for optimum purpose of parameters of reliability of units of hardware on the lead strength researches is offered.
Keywords: Strength, reliability, factor of a stock, mechanical characteristics, the likelihood analysis
At this paper we propose a new approach to processing knowledge through intelligent automation system travel agency. This approach is based on models of knowledge, interpreted using semantic knowledge. The principles of construction and operation of the architecture of the system to automatically obtain and process context information as an example of intellectual semantically-oriented system that provides travel services. Completed description of the ontology used by the tourist area. Demonstrated the use of context information from the knowledge base in the processing of queries to the system.
Keywords: ontology, automation of a travel agency, intelligent, contextual data, behavioral design patterns
An accurate solution of problem for a plane horizontal cutout is proposed where stress concentration subject to geometrics of the cutout is considered. This solution makes possible to solve problems relating to optimum designing of structures and machinery with similar technological elements.
Keywords: cutout, conjugation, problem, equation, solution, stress.
The construction of a two-dimensional tiling by a specific projection of three-dimensional cubic lattice is considered. Different a periodic tiling’s, consisting of equal rhombi, are obtained by different choice of the projection region. They are ordinary a periodic tiling, having local elements of symmetry group С6v and chiral trigonal stacking, built like chiral pentagonal Penrose’s quasilattice [1], which occurs in virus cap sides.
Keywords: Quasicrystal, quasilattice, two-dimensionalquasicrystal, chiral quasicrystal.

The article examines the construction of control plans and priorities ranks of information procedures for the implementation of the optimal information management in an automated information system. Constitute the basis for planning the hash ranks and priorities of both the subjects and objects of information interaction. The optimization process is provided by a choice of grades and corresponding control plans that define the extreme values of the objective function of the system.
Keywords: rank, priority, plan, information services, information procedure.

Based machine adaptation developed an algorithm that adaptively adjust the parameters of the membership function of design data. Adjustment parameters of the membership function is proposed based on the analysis of the reaction of the designer on the query results. This approach allows you to adjust power supplies design solutions to the corresponding values of logical variables based on subjective opinions of experts consecutive. The presence of a mechanism of adaptation helps to reduce the impact of one-off, drop out of the general concept, opinions.
Keywords: automatic adaptation fuzzy data correction.

Keywords: Challenges, Regional Bioenergetics, Peat, Energy Wood.
This scientific work is devoted developing questionnaire for poll of experts for the knowledge base information system of a choice of the channel distribution of the advertising message filling. Processing and the analysis of the data received at questioning of 20 experts are made. The knowledge base of information system of a choice of placing operative advertising kind is filled using received data.
Keywords: poll of experts, information system, operative advertising, and knowledge base, print advertising.
Proposed a mechanism for determining risk management strategies of labor protection, using the principle of ALARA (as low as reasonably achievable). This approach implies the maximum possible risk reduction achieved by actually available, but often limited resources of the enterprise. Results of risk control, including the choice of variability between conservation (abolition), decrease (prevention) or the transfer of risk.
Keywords: risk, risk management, risk control, health and safety.

In this paper we consider the problem of effective forecasting of electricity consumption for multiple objects in automatic mode. We propose an approach to automation of forecasting process, based on CRISP-DM. There were considered methods of computational intelligence for the data preprocessing - filling the gaps and identification of the emission, methods of construction and adjustment of forecasting models. As the computational basis are used connective models, based on neural networks and on constructive neural networks. There was shown the system architecture that implements the mechanisms of computational intelligence, and was presented the results of the tests.
Keywords: consumption of electricity, forecasting automation, computational intelligence, identification of the emission, connective models.
Development and improvement of local markets zernoprodovolstvennyh mining areas, as well as regional transaction sector agro-industrial complex of the Eastern Donbass centers contribute to the formation of institutional modernization of the regional economy. To identify the political, economic, social and technological factors in the external macro-environment that may significantly affect the business, structuring and formulation of the organization's strategy is an important analysis of institutional and market coordinates held in accessible form PEST-analysis.
