The relevance of the research topic is due to the problem of choosing options for converting property complex objects for the purpose of sustainable development of the city territory. The main task currently being solved at the state level is aimed at developing urban planning documents for the strategic development of urban territories. The developed documents have a positive impact on stimulating the development of a modern urban economy, high-quality territorial planning, lifting infrastructure restrictions in cities, and creating "smart territories" that are distinguished primarily by an effective management system and taking into account the opinions of the main stakeholders related to this territory. In this regard, there is a need to develop criteria to assess the prospects for the development of the territory of the municipality, taking into account its specific features and limitations. The purpose of the research is to create a simple, consistent system of criteria that is convenient for use in working with various objects of the property complex. To do this, first of all, it is necessary to identify the factors that affect the efficiency of the use of the property complex and the relationships between them, which will allow us to explore various options for the development of the property complex based on scenario modeling. The results of the study can be used to improve the efficiency of urban management, ensure sustainable development of the territory of the municipality, and improve the quality of life of the population.

Conducting land management activities is one of the most complex processes, as it includes a large complex of works aimed at studying the state of land resources, their distribution and the organization of the territory as a whole. A special place in land management is given to geodetic works, which are characterized by sufficient complexity of their implementation. In this regard, there are many questions concerning the organization and implementation of this type of work. This article will discuss the main stages and features of geodetic works in the implementation of land management measures.

The article deals with the forecasting of direct material damage to urban areas depending on the number of fires based on official data of the Ministry of Civil Defense, Emergencies and Elimination of Consequences of Natural Disasters, presented in state reports on the state of protection of the population and territories of the Russian Federation from natural and man-made emergencies for five years, based on the model of correlation analysis, which allows us to determine the degree of mutual influence of the parameters under consideration and the linear regression responsible for determining trends for subsequent years. The analysis of the reasons associated with the lack of the possibility of assessing the damage resulting from the fire of the structures of the building or its premises and its subsequent extinguishing in order to increase the economic efficiency of the cost examination during the restoration of real estate is an auxiliary basis for the construction of a correlation-regressive forecasting model.

The model of passenger traffic movement was evaluated to identify hidden patterns in the processes of passenger traffic formation using standard electronic computers with general-purpose software. Several sessions of simulating the movement of passengers between stops of urban passenger public transport, belonging to different levels of attractiveness of stops for passengers, were conducted. The features of the quasi-deterministic movement of passengers between stops of urban passenger transport that are not included in the list of stops of mass attraction of passenger traffic, and points of mass attraction of passengers are considered. Examples of typical patterns in the choice of destination stops and in the hourly flow of passengers from departure stops are given. The comparison of the number of daily visits to stops of mass attraction of passenger traffic, obtained by processing the simulation results with the initial statistical data, is carried out.

The purpose of this work is to develop an algorithm for recognizing shrinkage defects on metal alloys. The steps for image processing are described. When analyzing the algorithm, a description is presented for each step, followed by a software implementation. The final step, after using the methods of the algorithm, is to count the contours of the defects. To demonstrate the functionality of the software, random photos of the metal body in the section were taken, where defects in the form of gas pores can be directly observed. The software, with the correct selection of input data, processes the image with high accuracy, minimizing errors in calculating defects. Using the proposed algorithms reduces the diagnostic time. The article presents a comparative description of the manual and automated methods, showing the effectiveness of the second method in comparison with the first. To write the software, the Python 3.7 programming language was used, as well as the OpenCV computer vision algorithms library.

Reducing energy consumption in the design, installation and operation of engineering networks is implemented in the process of implementing investment construction projects. An energy service contract, like any economic agreement, requires a feasibility study. When strengthening the thermal protection of a building, it is necessary to determine both the design of the fences and translucent structures, and the payback period of the investment. The objective of the research is to develop and analyze a mathematical model of heat losses depending on the characteristics of the resistance to heat transfer of walls, windows and balcony doors. Classical dependencies do not allow applying standard mathematical analysis procedures. It is proposed to use a power function that assumes the availability of differentiation. The paper substantiates the form of such a function and provides an extended analysis of the effect of changes in the resistance to heat transfer of building structures on the transmission heat losses of a building, which allows arguing for the adoption of optimal technical and economic decisions.
