SURVEYING THE SECTOR
the virtual and physical worlds while optimising the parameters and sharing information with all parties involved in the interaction process , Yang Tao illustrated .
According to Gao Fengyong , the digital urban flood forecasting platform developed by Yunlu Technology achieved near real-time simulation of the urban flood process involving rainfall , ground water accumulation and pipeline drainage , allowing it to provide decisionmaking support and flood prevention and response guidance for government authorities through simulated pre-flood analysis , real-time early warning , and post-flood summary and analysis . Last summer , the platform had already contributed to flood control in Beijing , Ningbo , Jinan and other cities .
“ Alongside visualisation and simulation , a Digital Twin system is also intended to serve the physical entity through a digital replica to enhance the efficiency of physical production ,” Gao said . By collecting real-world information on the Internet of Things for the virtual world before analysis and simulation , the system can predict risks and achieve real-time mobilisation of resources , offering scientific support for decision-making in a timely manner .
However , excessive pursuit of digital technology and AI could lead to less focus on practical applications , resulting in insufficient integration of business rules and geometric models . “ Application matters most , but 80 % of Digital Twins are useless ,” Qiu Baoxing revealed , noting that for DT technology , application scenarios including Smart Governance , urban construction management , general urban management and emergency management are of paramount importance .
Yang Tao echoes that view . “ A fancy model does not necessarily work well ,” he said . Digital Twin cities must be tailored to solve specific problems in different scenarios , he added , and optimisation of urban governance cannot rely solely on
