The aim of this work is to develop a model of the agent changing its own structure, and movable in the fuzzy heterogeneous search space. The need of creating these search tools solutions is caused not only by lack of data on the solved optimization tasks, but also complex computational structures used in modern information systems. The agent is represented as a point in a fuzzy heterogeneous search space, the scale of each axis of the space built on the basis of the corresponding fuzzy sets. The movement of the agent along each axis is based on the permissible operations on the elements of the corresponding fuzzy sets. An example of agent movement along the axis specified on the basis of S-fuzzy sets. To determine the stopping agent developed automatic adaptation. It is shown that changing the position of the agent in the search space not always leads to the change of uncertainty inherent in the decision, described by the agent. The novelty of the approach is to develop adaptive algorithms move the agent in a heterogeneous search space. On the basis of machine adaptation is shown the scheme of movement of the agent in fuzzy search space along the axis specified with S - fuzzy sets.

For a long time in software engineering, there is a problem of a rather significant percentage of software project failures. One of the most frequent causes of such failures is non-optimal allocation of human resources, that is, the allocation of developers to tasks in accordance with their skills and the specifics of the task. Software development requires continuous improvement of skills and the degree of mastery of one skill can positively influence others associated with it. Due to the considerable number of skills there is a need in the expert system that allows you to track the changing skills and implement a near-optimal allocation of human resources. The impossibility of unambiguous evaluation of skills and partial overlapping with each other lead us to the fuzzy sets theory for processing of information about employees, rather than applying classical set theory or probability theory. At the end of the article, the most significant skills of IT specialists are presented.

Solved calculation of equilibrium distribution of Ge and the density of elastic energy in semiconductor film SiGe/Si. Built the 3D model of flat film with pyramid islands and dislocations. Calculation of elastic deformation is made using the finite element method. In this model takes into account the uneven distribution of Si and Ge due to threading dislocations, misfit stress and dislocation loops. The results showed that in the two-part elastic layer SiGe provision balance dislocation is located in the depth of the inconsistencies of the film and not on the boundary of film-substrate. This conclusion applies to the penetrating dislocation, while changing the orientation of dislocation much changes box elastic stresses and distribution component of Si and Ge in the film. The results of the calculation model of the sample, including prismatic dislocation loop, shown a significant impact on the value of the elastic energy of the film. While accounting for the effects of non-uniform distribution of SiGe alloy component does not result in a significant change in the magnitude of elastic energy model and critical values of height. According to calculations, taking into account the heterogeneity of the distribution component of the alloy transition to the formation of Epitaxial islets on the film surface occurs at lower values of their critical size, especially when small concentrations of Ge in the alloy. The results of calculation of the elastic energy of the film received at work, can be applied to calculate the conditions of occurrence of defects in nanometer dimension on the original flat free surface of semiconductor films.

The article briefly describes the technical solution for the use of specialized fiber-optic cable embedded in ground wire (OPGW) on the sections of electric Railways AC. The technical solution is to combine in a single conductor functions return conductor and fiber optic communication lines. Are given the relevance of such decisions and some peculiarities of its implementation. The main part of the article examines to the selection options return conductor with combined functions. The article describes the theoretical dependencies for the combined selection of the conductor based on the thermal resistance criterion. As one of the main passport parameters of the OPGW cables is the section of the metal component, the percentage of their content and the variation percentages are used in calculations to determine the electrical resistance of the cable and the magnitude of the permissible current. This approach allows to determine the parameters of the cable based on the criterion of reliability and allows to obtain the cable composition for a subsequent order from the manufacturer. The algorithm of selection combined return conductor that contains two stages: pre-selection based on the reference data, the choice of the real parameters from the manufacturer.
