Cyber-Physical Systems Resilience
Building resilience into the design, monitoring, recovery, and reconfiguration strategies of cyber-physical systems
Past efforts to enhance system resilience have focused mainly on understanding the interdependency of socio-technical systems and improving interoperability among physical systems.
However, the future generation of infrastructure systems will predominantly be cyber-physical in nature, as is already the case with systems such as the mass rapid transit (MRT). This brings new challenges but also opportunities to achieve more efficient and accurate monitoring, as well as more effective system control, protection and recovery.
Cyber-Physical Systems (CPS) refer to physical systems with integrated data acquisition, analysis, and intelligent advisory abilities that interact with humans to deliver their intended functions. A unique feature of CPS is the massive amount of data available at the cyber level, which contains rich information about system conditions.
New frameworks and methods are needed to use condition-monitoring data more effiently to manage the health of the systems and for efficient operation.
Expected outcomes
- Focused on enhancing CPS resilience through advanced system design and operation, this research module will identify key factors that influence CPS resilience and provide insights into ways to design CPSs for enhanced resilience and into potential issues in the operational resilience of modern CPSs.
- Resilient system design, effective system monitoring, recovery schemes, and reconfiguration strategies will be developed with the goal to better understand and improve interactions among concepts of operation, automated recovery and data networks and their integration into system design.
- The frameworks and methods developed could benefit policymakers and practitioners in planning and regulating system recovery following different types of failures.
