Key technologies of the emergency platform in China

An emergency platform is an informatization support platform for disaster information perception, disaster situational awareness, and emergency decision command. This is a key tool for ensuring the efficiency and effectiveness of emergency responses. Numerous large countries have conducted in-depth research on the key technologies of emergency platforms. Over the past 20 years, with the reform of emergency management mechanisms, China has developed two generations of emergency platform systems. This paper reviews the two generations of emergency platforms and summarizes their key technologies including multi-source-based monitoring and early warning, multi-hazard risk assessment, “scenario-response”-based decision support, synthetical forecasting based on incident chain, and emergency common operational picture (COP) for command and dispatch. Future research directions for the next generation emergency platforms are also proposed.
