There was a need for geotechnical monitoring during construction of underground facilities. The organization of monitoring control tensile forces in the concrete anchors. Comparison of experimental and calculated data, which revealed that the deviation does not exceed 19%.

In the article numerical simulation of the interface zone of a tunnel with a vertical barrel by the finite element method is considered. The numerical spatial model is a fragment of a rock mass with a size of 80 to 90 meters, in which the tunnel is connected by a span of 6.0 m, adjacent to the vertical trunk. The mating and trunk in the area under consideration are fixed with reinforced concrete lining 500 mm thick. A universal spatial isoparametric eight-node finite element is used to break up the model. The dimensions of the finite elements on the outer regions of the model were 2.5 - 5.0 m, on the inner - 0.25 - 0.5 m. Thus, the principle of combining dense and rarefied grids was used to reduce the amount of information describing the numerical model. The problem was solved in an elastoplastic formulation by a stepwise iteration method. As a result of calculations, all the components of the volumetric stress tensor in the finite elements of the lining and the rock mass, movement and deformation in the nodes of the finite elements were determined. With the help of the developed numerical models, a series of calculations was performed, an array of data was obtained on the stress-strain state of the lining in the zone of coupling effect, quantitative and qualitative analysis was performed. It is established that in characteristic zones of the influence of conjugations, a significant increase in the intensity of equivalent stresses is observed, which leads to a reduction in the load-bearing capacity of the lining by 2 times or more in comparison with extended sections of underground structures. To increase the efficiency of maintaining interfaces during tunnel operation, it is necessary to justify the control actions taking into account the dynamics of changes in the stress-strain state of the lining in space and time.

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.
