Resilient infrastructure planning involves theoretical considerations of designing infrastructure systems to withstand and recover from natural and human$-$induced disasters. Construct a detailed theoretical framework delineating principles of resilience engineering, including risk assessment, adaptive capacity, and system robustness. Explore theoretical models for quantifying infrastructure resilience metrics, such as reliability, redundancy, and resourcefulness, and discuss theoretical approaches to incorporating resilience considerations into infrastructure planning, design, and management processes, aiming to enhance community resilience and sustainability in the face of uncertain and evolving threats.
