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
