Your household can survive a power outage only if someone knows where the flashlights are, where the water is stored, and how to use the manual pump—all invisible vulnerabilities until you map them. Dependency graphs expose these hidden single points of failure so you can add backup systems before crisis forces improvisation.
A dependency graph in household preparedness is a visual or computational map that shows how each resource, person, and action in an emergency plan relies on other resources, people, and actions — revealing which nodes are critical connectors whose failure would disable large portions of the plan. It is the structural backbone that makes redundancy planning meaningful rather than arbitrary.
AI can construct these graphs automatically by parsing your emergency documentation, interviewing you about your household setup, and running graph-theory algorithms to score each node by its criticality. The output tells you precisely which supplies to stockpile, which roles need a backup person, and which assumptions carry the most downstream risk.
