The process of overcoming the risks of destruction of the life world by young spouses is studied. Methods of cognitive modeling are used. The theory of adaptive control is chosen as the basic paradigm. This allowed the study to build on the existing theoretical basis of structural analysis of adaptive systems with models in the adaptation circuit.To use the practical experience of cognitive modeling of systems with the inclusion of a person in the adaptation circuit, for example, training models based on a double feedback loop. It is proposed to use the technology of solving problems, based on the experience of past situations, namely, the technology of output based on precedents (Case-Based Reasoning, or CBR). A generalized adaptive model of reducing the risks of destruction of the life world of a young family on the basis of a double CBR – cycle is developed. The model describes the process of self-development of young spouses through continuous training in complex problem situations

The article deals with the problem of the functional state of the bridge park in Russia. The statistics of the number of bridges, newly built bridges. Attention is focused on the inconsistency of old bridges with modern regulatory requirements for safety, carrying capacity, and carrying capacity. Noted on the relevance of flood impact on bridges and roads. The causes of occurrence are described. The problem of flood forecasting is highlighted. Examples of accidents of bridge structures from the effects of water flow are given: sediment, roll of supports and abutments, erosion of the embankment approach. Based on the situation in the city of Chita, the statistics of the frequency of flooding in different years are given, the critical levels of these disasters are indicated, and statistics on the consequences of the impact of the flood is given. The impact of the normative water flow is considered, and it is proposed to analyze the effect of the excess flow arising from the maximum level of bottling. Presents the results of calculations for which comparisons are made of various approaches to determine the depth of erosion of the channel.

Abstract: the results of the analysis of existing and projected volumes of export cargo transportation in the freight-stressed areas of the Russian railway network to the ports of Azov-the black sea basin are Presented. It is established that the growth of traffic ahead of the development of the transport capacity of the studied railway directions. In this regard, foreign and Russian experience in the development of growing volumes of cargo transportation in terms of infrastructure constraints due to the organization of heavy train traffic has been studied. The measures of development of heavy traffic of trains are offered. The method of calculation of efficiency of the organization of heavy traffic on one of sites of the North Caucasian railroad is given.

The distribution center is one of the main elements of the distribution system, which forms the structure of the movement of resources. It is responsible for ensuring the efficient allocation of the flow of resources. The effective location of the distribution center allows you to reduce the cost of allocating resources to 30%. The method of solving the problem of effectively securing demand zones for a particular distribution center is proposed in this article. The uncertainty of the initial parameters is taken into account when solving this problem. The result of solving the problem of determining the effective location of distribution centers is a set of fuzzy intervals. These intervals determine the coordinates of the location depending on the parameters of the task, namely, the demand of consumers, the capacity of distribution centers, the distance between the resource consumers and the center. The location of the distribution center will be determined not by a specific numerical value, but by a fuzzy interval that will determine the region of the best location. A software application is developed that allows you to specify parameters in a fuzzy interval form, on the basis of which the results of solving the problem are formed. The cost of delivering resources to consumers changes significantly with the change in the number and location of distribution centers, so the issue of rational distribution and the number of centers is important. This task becomes especially relevant when a new distribution system is being designed, or the existing system is being modernized.

Keywords: distribution centers, the demand, the uncertainty of the initial parameters of the fuzzy intervals, potential interactions, grouping

It is considered a centrally symmetric stress-strain state of the rock mass near the underground spherical cavity taking into account the technological heterogeneity of the rocks of the near-edge region. The mathematical model was developed and analytical solutions were found for this problem. The technological heterogeneity of the elastic properties of the rock mass material was modeled by a radially inhomogeneous coefficient of elasticity at a constant Poisson's ratio. The variable coefficient of elasticity for heterogeneous rocks was approximated by a generalized polynomial with undetermined coefficients. On the basis of experimental data, a numerical calculation of the stress-strain state components for the problem was carried out, and characteristic effects were detected.
