Lifeline systems—such as energy, water, transportation, telecommunications, and healthcare—form the backbone of societal resilience. Yet, their interdependencies often create systemic vulnerabilities where failure in one domain cascades across others. This question seeks expert input on the most effective methodologies for modeling, mapping, and stress-testing these cross-sectoral interdependencies. Topics may include network theory, systems dynamics, agent-based modeling, graph analytics, and geospatial correlation frameworks. Responses should consider real-world applicability for disaster planning, infrastructure investment, and national resilience strategies.
