Urban planning is a complex process of controlled development of the city,\u0000 and the problem of digitalization of the city as a system as a whole has not lost its\u0000 relevance. The research examines the problem of selection, application and integration\u0000 of modern information technologies for modeling the urban environment and creating\u0000 digital duplicates of city objects as components of the Smart City system. An overview\u0000 of the main IT for the application of the methodological platform of information\u0000 modeling of cities (City Information Modeling) based on Building Information Modeling\u0000 (BIM), Geographic Information System (GIS) and Internet of Things (IoT) technologies,\u0000 which make it possible to combine city data of various spatial scales and time\u0000 dimensions. A conceptual IT scheme for urban space management is proposed based on the\u0000 integration of three components: the Artificial Intelligence system, Big Data\u0000 technology, and the CIM methodological platform. The requirements for the selection of\u0000 information technology for the creation of a digital double of an urban object were\u0000 studied, which made it possible to propose an integration scheme of IT modeling of the\u0000 urban environment and the creation of a digital double of the city. Such integration\u0000 will help to efficiently process large and complex data sets, use information about the\u0000 past and present to predict the future, implement digital reproduction of a physical\u0000 object and create a digital urban spatial object, namely a CIM object, which should\u0000 become a digital basis for intelligent planning, construction, management and operation\u0000 of a smart city.","PeriodicalId":321731,"journal":{"name":"Management of Development of Complex Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127679539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The\u0000 urgency of the chosen topic is due to the rapid return of a large number of people in\u0000 our country to eternal Christian values after many years of forced atheism. These facts\u0000 significantly contribute to the current intensive restoration of religious buildings,\u0000 the construction of new temples, the revival of monasteries, the improvement of places\u0000 of pilgrimage, the optimization of proper organizational and territorial church\u0000 structures, the implementation of spiritual-educational and other charitable activities.\u0000 Our days are characterized by global social changes, such as the widespread introduction\u0000 of market relations in all spheres of life, land, medical, educational reform,\u0000 decentralization of state power and more.

The waste of the mining and processing\u0000 industry accounts for the largest amount of waste among all existing branches of human\u0000 economic activity. The most rational area of application of by-products of mining\u0000 enterprises is the industry of non-metallic building materials. This is mainly due to\u0000 their relative environmental safety. Man-made deposits, as the enrichment technology and\u0000 the corresponding equipment are improved, already have and may in the near future\u0000 acquire significant industrial importance. Taking into account their negative impact on\u0000 the environmental where they are located and the lack of free territories and funds for\u0000 the construction of new dumps and tailings storage facilities, it can be argued that\u0000 solving issues related to the development of man-made deposits is becoming particularly\u0000 relevant. Considering this, one of the possible fields of their use is environmental\u0000 technologies. Ecological engineering allows the introduction of biological and chemical\u0000 methods and systems that exist in nature for the study and design of engineering systems\u0000 and modern approaches and technologies. Industrial ecology (IE) is the study of material\u0000 and energy flows through industrial systems. The global industrial economy can be\u0000 modelled as a network of industrial processes that extract resources from the Earth and\u0000 transform those resources into products and services which can be bought and sold to\u0000 meet the needs of humanity. Industrial ecology seeks to quantify the material flows and\u0000 document the industrial processes that make modern society function. Industrial\u0000 ecologists are often concerned with the impacts that industrial activities have on the\u0000 environment, with use of the planet's supply of natural resources, and with problems of\u0000 waste disposal. Industrial ecology is a young but growing multidisciplinary field of\u0000 research which combines aspects of engineering, economics, sociology, toxicology and the\u0000 natural sciences. Industrial ecology has been defined as a \"systems-based,\u0000 multidisciplinary discourse that seeks to understand emergent behavior of complex\u0000 integrated human/natural systems\". The field approaches issues of sustainability by\u0000 examining problems from multiple perspectives, usually involving aspects of sociology,\u0000 the environment, economy and technology.
