Smart city logical framework and digital-twin platform technical requirements

Abstract

Abstract:

Cities are open, complex, and dynamically changing “nature-society” mega-systems, where various functional and structural subsystems continuously interact and influence one another, forming the inherent logic of urban operations. Smart cities present viable solutions to address the broad systemic issues within urban areas. However, the traditional vertical coupling architecture, despite its self-sufficiency, has failed to align effectively with urban operational logic, resulting in numerous “data islands” and “information silos” that impede the process of high-quality urban development. This article adopts an urban system perspective, grounded in the developmental needs of smart cities in the information and communication technology (ICT) era. It proposes a lateral coupling system architecture that facilitates joint construction and sharing for smart city development from theoretical, technological, and methodological standpoints. Furthermore, the study seeks to clarify the concept of the urban system from a philosophical perspective and to identify the key technical requirements for a digital twin platform, thereby providing guidance for the engineering practice and innovative application of smart cities.

Key words: smart city, digital twin, urban informatization, engineering logic, operating system
