The arrangement of protective structures of civil defense is currently vitally important, especially for populated areas located near the combat zone. A pressing issue in the design of shelters is the correct determination of the volumes of air exchanges required to ensure the stay of those sheltered during the standard periods. An analysis of changes in climate and microclimate parameters over the past years and methods for calculating air exchange in protective structures was conducted. A classic model of the process of changing the temperature and humidity of the air with a variable coefficient of inclination of the beam of such a process was built. The redundancy of air exchanges calculated according to the data and methods of the latest regulatory document is shown, leading to an increase in capital costs for the arrangement of a shelter.

Currently, one of the main factors influencing the formation of architecture is the functional purpose of the building, since it determines the essence of the architectural object. The purpose of the scientific work is to study the influence of building functions on the historical architecture of Europe and their impact on the development of modern architecture. This article sets the objectives of studying the classification of functional purposes of buildings, conducting a retrospective analysis of the development and formation of architectural styles in Europe, based on world design experience and the conducted research to identify the influence of the building function on its planning and volumetric-spatial solutions in the process of architecture development. The research method is the analysis of the historical architecture of Europe from the time of the inception of architecture to the present day, carried out on the basis of world design experience in different eras. In the course of the study, four main trends in the development of the functions of modern architecture were identified: integration with nature, creation of adaptive spaces, multifunctionality and development of new functions. It is concluded that the building function played the most important role throughout the entire period of architecture formation, which led to the emergence of a huge variety of building types today and made a significant contribution to the development of architecture of the XXI century.

This paper considers the problem of task scheduling in manufacturing systems with multiple machines operating in parallel. Four approaches to solving this problem are proposed: pure Monte Carlo Tree Search (MCTS), a hybrid MCDDQ agent combining reinforcement learning based on Double Deep Q-Network (DDQN) and Monte Carlo Tree Search (MCTS), an improved MCDDQ-SA agent integrating the Simulated Annealing (SA) algorithm to improve the quality of solutions, and a greedy algorithm (Greedy). A model of the environment is developed that takes into account machine speeds and task durations. A comparative study of the effectiveness of methods based on the makespan (maximum completion time) and idle time metrics is conducted. The results demonstrate that MCDDQ-SA provides the best balance between scheduling quality and computational efficiency due to adaptive exploration of the solution space. Analytical tools for evaluating the dynamics of the algorithms are presented, which emphasizes their applicability to real manufacturing systems. The paper offers new perspectives for the application of hybrid methods in resource management problems.

The article is devoted to the study of the influence of the choice of the calculation scheme on the accuracy of the engineering assessment of the behavior of monolithic reinforced concrete frame structures. Various types of models are considered: rod, plate and volumetric, taking into account both linear and physical nonlinearity. It is emphasized that the adequacy of accounting for the spatial interaction of elements, the reliability of the assessment of forces and stresses, as well as the possibility of optimizing design solutions, especially under seismic and wind loads, depend on the correctness of the adopted calculation scheme.
As part of the study, a single-span reinforced concrete frame was modeled, the load on which varied from 5 to 55 kN. A comparison of the calculated results with experimental data was carried out. It is shown that models that take into account physical nonlinearity and use more detailed modeling (for example, volumetric finite elements) provide the greatest accuracy in predicting deflections and stresses in the structure.
The obtained results confirm the necessity of a careful approach to the choice of the calculation scheme in design, especially in the design of high-rise buildings and structures in seismically dangerous areas. Recommendations are made on the rational use of models of different levels of detail in engineering practice.

In territorial planning, the choice of industrial territories is crucial for the state. The advantageous location will allow for the creation of labor application points to ensure stable economic growth. Understanding and taking into account the parameters of the formation and further functioning of such territories always require an integrated approach, that is, taking into account both economic and social, spatial and environmental factors. When planning, the accessibility of transport infrastructure, the availability of raw materials, tax incentives and other economic incentives can be key when choosing a particular area for the location of industrial facilities on it. An integrated approach can become especially relevant not only when planning new undeveloped territories, but also when converting existing large production areas.
