JIIRP - UBC Project Overview
Data Flow
Infrastructure Network A(e.g. Water Network)
Infrastructure Network B(e.g. Emergency Services)
Hospital
Fire trucks
Emergency shelters
Systems’ internal structure
Interdependencies between systems (Physical, Cyber, geographical, organizational)
An external event that perturbs the normal state of things
An internal event that perturbs the normal state of things
Infrastructure Interdependencies: Objects of Study
