Towards Event-centric Cyber-Physical-Social System for Disaster Management

Disasters may be due to meteorological events, geo-logical events or man-made. Approximately 700 disasters occur each year with annual world-wide impact of over 100B/year. Cyber-Physical Systems (CPS), which are smart networked systems with embedded sensors, processors and actuators designed to sense and interact with the physical world (including the human users) in real-time, provide safety-critical applications where the proverbial "blue screen of death " can have catastrophic consequences, can dramatically increase the situational awareness of emergency responders and enable an optimized response through all phases of disaster events, i.e., prevention, preparation, response, and recovery. However, significant energy-efficiency-related research challenges arise because of disaster management requirements for the quality of service and information. Energy-efficient communication, computing and control are desirable for CPS for disaster management. In the paper, we propose a Cyber-Physical-Social System (CPSS) framework for disaster management by combing CPS and the society of human beings. We adopt an Event-Linked Network (ELN) model to achieve green communication and computing in CPSS for disaster management and apply the model to disaster management of earthquakes as a case study. We believe the CPSS mechanism with the included disaster resilience will promote the disaster management which includes the disaster resilience.
