Exploring Opportunities and Challenges in Sustainable and Smart Cities Through the Lens of Smart Technologies

This paper offers a tutorial based on a survey, focusing on the technologies that support and the potential applications within smart cities. It begins by providing a thorough definition of smart cities concepts from both industrial and academic viewpoints, then proceeds to investigate various applications within smart urban environments, spanning from the Internet of Everything to intelligent healthcare, cloud manufacturing, smart additive manufacturing, and geospatial intelligence. Emphasizing key-enabling technologies, the paper underscores the importance of achieving consistent harmony between human and machine efficiency. With the aid of emerging applications and supporting technologies, smart technologies have the potential to augment manufacturing output and enhance customer satisfaction. However, to fully realize the concept of smart cities in the foreseeable future, several challenges and open issues such as security, privacy, human-robot collaboration in industrial settings, scalability, and the skilled workforce need to be effectively addressed. This comprehensive approach aims to provide solutions to contemporary urban challenges while advancing the smart city concept.
