In the conditions of modern economy, where optimal personnel decisions are very important for any organizations, especially in the dynamically divisive electric power industry, the issue of developing an intelligent system for making personnel decisions in the electric power industry becomes relevant. This paper analyzes the existing tools for selection of candidates for vacant positions including managerial positions and vacancies from the electric power industry. Based on the analysis and earlier research, a competency profile of managers of the electric power industry is formed. The development of the program product was conducted using various programming languages in the Visual Studio development environment. The program represents a dynamic and interactive process of managerial decision-making, where users face different scenarios to assess the formed competencies, with the output of a detailed report on their skills, which provides employers with an objective assessment of the candidate's potential for a vacant managerial position.

The problem of a comprehensive assessment of the quality of construction production is considered. The problematic nature of such a procedure is noted, due to the fact that construction production is a multifactorial process in which a large number of material, financial and labor resources are used, with different units of measurement. It is proposed to consider the complex indicator "Integral indicator of the quality of construction production" based on the transformed Harrington desirability function, which allows taking into account many factors having different-sized controlled parameters.

Keywords: quality of construction production, integral index of construction quality, quality coefficient, generalized utility function, Harrington desirability function

The task of planning the sending of messages of known volumes from source points to destinations with known needs. At the same time, it is assumed that the costs of transmitting information on the one hand are proportional to the transmitted volumes and the cost of transmitting a unit of information over the selected communication channels, and on the other hand are associated with a fixed subscription fee for the use of channels that does not depend on the volume of transmitted information. An indicator of the quality of the plan with such a statement is the total cost of sending the entire planned volume of messages. A comparative characteristic of the effectiveness of methods for obtaining optimal plans using a linearized objective function and an exact solution by one of the combinatorial methods is carried out.

In this paper, the possibility of applying graph neural networks (NN) to study the structure of copper centers of zeolites is considered. The dataset used for NN training was prepared using the FDMNES software based on the finite difference method and included more than 2100 Cu K-XANES spectra for Cu-MOR. The performed study demonstrated the capability of graph neural networks to reproduce the Cu K-XANES spectrum corresponding to a particular model of the copper center in the zeolite framework.

The authors, having examined the main buildings, structures, and amenities located on Lenin Avenue in the capital of the Kabardino-Balkarian Republic, showed that, although there are almost no old buildings of the pre-revolutionary era in the Ciscaucasian city, it is rich in architectural objects in the pleasant, unpretentious Stalinist Empire style. Nalchik can be called a classic city in the mountains. The peculiarity of the city is a wide and spacious avenue with a high level of greenery, with a high level of improvement. This is the central and longest street in the city. The length is more than five kilometers. Lenin Avenue is an important landmark, which is essential for the city for the normal life of modern society. The center of the capital was formed around the avenue, where squares, residential buildings and public buildings, various establishments, recreation areas, as well as interesting architectural objects are concentrated. Prospect Lenina can be proudly entered into the register of cultural heritage objects as it meets the requirements for classic avenues.

No modern metropolis can be imagined without such public transport as the subway. The subway is the most important element of infrastructure for large cities and provides a convenient, fast, safe and environmentally friendly way for the population to travel. The construction of the subway is a long and complex process, which requires large investments and consideration of many factors. During the construction of metro stations it is necessary to carry out work on laying utilities, such as electric cables, pipelines for water supply, sewerage, ventilation and other systems. These utilities ensure the operation of the stations and comfort for passengers. Erection of engineering networks in the subway is a complex and multi-year process that requires application of new technologies and high qualification of specialists. However, proper planning and work coordination can significantly reduce time and costs of the project, ensuring uninterrupted operation of metro stations in the future. The work is devoted to the peculiarities of construction of the Moscow subway, which is considered one of the largest subways in the world in terms of length and passenger traffic.

The study findings on the utilization of ethyl silicates for enhancing bitumen properties are showcased. The impact of ethyl silicate grades 28, 32, and 40 on the characteristics of BN 90/10, BN 70/30 construction bitumen, and BND 60/90 road bitumen was evaluated. On the basis of the conducted studies, grades of bitumen and ethyl silicate were selected, the compositions based on which have the best performance. The compatibility of ethyl silicates with bitumen was tested. It has been established that a smaller amount of ethyl silicate is combined with high-quality bitumen. Based on the infra-red spectra, it was shown that there is no chemical interaction between bitumen and ethyl silicate, but a hydrolysis reaction occurs with the formation of hydrogen bonds. It has moreover been determined that ethyl silicates exhibit both plasticizing and structuring effects on bitumen, resulting in improved frost resistance of polymer-bitumen compositions. Requirements for materials aimed at waterproofing of structures for soil and concrete constructions have been developed and presented. In order to increase the low-temperature limit of applicability of polymer bitumen compositions, additives of liquid oligomeric rubbers from the Yaroslavl synthetic rubber plant (SK-1), as well as latexes from the Krasnoyarsk and Omsk plants were studied together with ethyl silicates. Recommendations are given on the use of ethyl silicates in waterproofing mastics and asphalt polymer concrete.

Geodesic control plays an important role in the reconstruction of cultural heritage sites. It allows the accurate determination of the geometric parameters of historic objects, which can be particularly important for restoring their historic size and shape to achieve the most accurate match to the original appearance. Geodetic work is carried out to support the accuracy of design and construction. They allow you to monitor the consistency of the design documentation and the actual work performed. This can help avoid errors and additional work during the construction phase and ultimately ensure a higher quality of reconstruction. This paper describes geodetic support during the reconstruction of the residence of Patriarch Kirill. Located on a huge territory the complex has a high religious-historical and cultural significance, which determines the quality of geodetic control at all stages of reconstruction and construction works.
