We define a smart city (SMART CITY) as an urban area that uses various types of electronic sensors to collect data, in order to provide the information needed to manage assets and resources. This includes data collected from: citizens, devices and assets that are processed and analyzed for monitoring and management. It also involves the management of traffic and transportation systems, as well as power plants, water supply networks, police, etc. The concept of a smart city combines information and communication technology and various physical devices connected to the network to optimize the efficiency of available services. The smart city system enables the city authorities to review the development of the city, as well as the possibility of further developing the system for additional improvements in the future. Information and communication technology is used to improve the quality of life in smart cities and reduce the cost of living. Smart applications have been developed to manage city flows and enable real-time reactions. Therefore, a smart city can be more ready to respond to the challenges of everyday life using advanced mobile technologies and artificial intelligence. The case study on Dubrovnik deals with the management of Dubrovnik as a smart city, as well as the development and implementation of management solutions for a unique tourist destination.
