Robustness of Interdependent Cyber-Physical Systems against Cascading Failures
There is a consensus that integrated cyber-physical systems (CPSs), such as the smart-grid, will emerge as the underpinning technology for major industries. A major concern regarding such systems is the seemingly unexpected large-scale failures. Such events are often attributed to a small initial shock getting escalated due to intricate dependencies within and across the individual (e.g., cyber and physical) counterparts of the system. This phenomenon, also known as cascade of failures, has the potential of collapsing an entire infrastructure.
