Research Path ============= Operational Resilience Engineering is being developed through a sequence of linked theoretical, methodological, and applied efforts. Near-term work -------------- * Specify vulnerability and resilience spaces and their relation. * Formalize system state, performance, operational boundaries, and feasibility. * Develop the paired \(2 \times 2\) frameworks for resilience and vulnerability. * Clarify the role of interpretation and perspective in decision models. * Construct worked examples for critical infrastructure systems. Planned research outputs ------------------------ * Foundational conceptual and technical notes. * Formal mathematical definitions and propositions. * Infrastructure case studies and computational demonstrations. * Reproducible code and model artifacts. * Preprints and peer-reviewed publications. This roadmap is intentionally provisional. The site will distinguish clearly between established foundations, current working formulations, and released citable research artifacts.
