Dynamic recovery of critical infrastructures: real-time temporal coordination
This paper takes a systems engineering approach to the problem of operations coordination among multiple infrastructures to minimise the impact of large disasters on human lives. Temporal coordination is essential to avoid bottlenecks in the simultaneous recovery of multiple infrastructures systems. A solution framework is presented in terms of multiple-delay difference equations which bring out the temporal interdependencies among infrastructures. The present work is part of an effort by the Government of Canada, through the Natural Sciences and Engineering Research Council (NSERC) and Public Safety and Emergency Preparedness Canada (PSEPC) to fund research to develop innovative ways to mitigate large disaster situations.
