A household resource chain breaks when one link fails: heating fuel is useless without a functioning furnace, food is pointless if no one can cook it, water treatment depends on containers and knowledge. Modeling these chains reveals single points of failure and shows where one backup system protects multiple resources.
A dependency graph is a structured map showing how resources, systems, and people in a household rely on each other, revealing which failures will trigger downstream consequences across your emergency plan. For example, a dependency graph might reveal that your backup generator powers the medical device that your shelter-in-place plan assumes will function, creating a hidden vulnerability if fuel runs out.
AI can generate and analyze these graphs from information you provide about your household, automatically identifying critical nodes where a single failure cascades into multiple plan breakdowns. This technique moves emergency planning beyond simple checklists into a systems-level understanding of how your specific household will actually hold up under pressure.
