The Impact of Cutting-Edge Technologies on Smart City Supply Chain: A Systematic Literature Review of the Evidence and Implications

As cities have become more populated and urbanized, governments have faced several challenges in effectively managing cities. To overcome these challenges, transitioning to smart cities using advanced technologies has become a viable solution. This article primarily centers on the role and implementation of operational excellence (OPEX) and advanced technologies, such as the Internet of Things (IoT), blockchain, artificial intelligence, cybersecurity, 5G, and edge computing in managing smart cities, particularly in the context of the supply chain. A systematic literature review, conducted in Scopus and Web of Science databases, identified 33 articles related to the application and role of advanced technologies and OPEX in the supply chain of smart cities (SCSC). The article revealed that the IoT and blockchain are the most commonly used technologies to create a secure and transparent platform for data collection and storage in the SCSC. Advanced technologies enable process monitoring and control, increasing customer trust and satisfaction in SCSC. However, integrating advanced technologies with OPEX for SCSC management still needs to be explored. Despite the progress in developing and improving SCSC using advanced technologies and OPEX, much still needs to be done. The article highlighted several research gaps in this area that need to be addressed in future research.
