The subject of the article's research is the methods and capabilities of information technologies and electronic devices-carriers of the Internet of Things to develop a combined system with the aim of determining the characteristic features. The purpose of the work is to study and analyse the use of smart technologies for a smart city based on a combination of information technologies and Internet of Things devices, as well as to identify key criteria for the development of modern cities with an impact on improving the quality of life for the population. In accordance with the objective, the following tasks have been formulated: to consider the main possibilities of using information technologies in combination with electronic measuring and computing devices of the Internet of Things; to determine the features of building information technology models with the connection of Internet of Things devices to switching networks; analyse the architecture of fog and edge computing for Internet of Things devices; to identify the main risks and cybersecurity issues with encryption of Internet of Things device data using encryption algorithms; to determine the main criteria for each individual system of smart technologies for a smart city; to determine the feasibility of needs with the needs of the population based on the defined criteria. An urgent problem is to identify and study the main possibilities of using smart technologies in order to identify problems related to the feasibility of meeting the needs of the population. This paper considers and investigates the impact of a combined system with a set of smart technologies on improving the quality of life using eight branched systems, namely: "smart" infrastructure, "smart" economy, "smart" environment, "smart" governance, "smart" transport, "smart" services, "smart" people and "smart" life. The set of criteria of each system needs to be analysed and matched with the needs of the population so that the combined smart city system can provide the population with conditions that can improve the quality of life. The scientific novelty of this paper is the development and implementation of the concept of a combined smart city system to meet the needs of the population while improving the quality of life. Results achieved. Smart technologies are based on the use of information technology, data and innovation to achieve sustainable development of individual systems with the definition of criteria, which analyses the following: "smart" infrastructure contributes to the creation of a convenient, efficient and sustainable urban environment; "smart" transport improves traffic and mobility, reduces the negative impact on the environment, increases safety and convenience for citizens; "smart” governance makes a significant contribution to the development of various sectors, promoting the efficient use of resources and improving the quality of life with sustainable development for the population; "smart" environment contributes to the conservation of natural resources, reduces the negative impact on the environment and ensures an improved quality of life for the population; "smart" services ensure the sustainable development of healthcare, finance, tourism logistics, which helps to create a more convenient and efficient environment for consumers, contributing to the improvement of the quality and availability of various services; "smart" people make a significant contribution to the development and application of new opportunities for the development of information technologies in combination with the Internet of Things; "smart" life ensures sustainable development for citizens through the use of technology to improve aspects of everyday life; "smart" economy makes a significant contribution to the implementation of technological solutions and contributes to a more efficient functioning of the country's economy. Conclusions. The results of the study demonstrate the impact of the combined smart city system on improving the quality of life, which is explained by determining the compliance with the needs and conditions of the population. Thus, the combination of criteria of each smart technology allows transforming the city into a general combined system with digital services for the provision of services. The vector of further research will be aimed at developing the considered combined system using digital technologies in order to create a digital model of the "city of the future using appropriate software.
