Chronic hazards associated with a changing climate may necessitate difficult adaptation decisions in many coastal communities. Computational tools that account for uncertainties in future climate conditions, impacts, and human responses are needed to
The Global Positioning System (GPS) is the most prevalent Global Navigation Satellite System (GNSS) that provides Position, Navigation, and Timing (PNT). GNSS vulnerability is well-known, and the search continues to find another independent system that can
This research brief provides a research summary and research advancement details for the functional recovery post-earthquake performance objective being advanced by NIST's Engineering Laboratory. A current update on the status of functional recovery
During the COVID-19 pandemic and concurrent natural disasters, small businesses were hard hit by decreased consumer demand, supply chain interruptions, and increased costs. To understand the impacts of these complex, large-scale events and organizations'

This Volume 2 report serves as a companion document to Volume 1 that presents a framework to guide the reader through steps to achieve system level functional recovery of lifeline infrastructure systems exposed to earthquake events. The proposed framework
Community resilience planning is challenging as it involves several large-scale systems with interdependency, populations with diverse socio-economic characteristics, and numerous stakeholders. This study introduces a new optimization model to decrease a

This report demonstrates by examples and case study as a proof of concept the use of loss amplification and risk aversion in benefit cost analysis (BCA) for community resilience planning. The report uses the NIST Economic Decision Guide Software (EDGe$)
While recent advancements have been made in performance-based earthquake engineering to stochastically quantify functional recovery times for individual buildings, most of the modern building stock is designed according to prescriptive codes and standards
