Two-Stage Resilience Evaluation for Healthcare Networks from the Adaptability and Recoverability Perspective

Abstract

Earthquake hazards have the potential to cause significant disruptions in healthcare networks. This study introduces an innovative resilience assessment framework that addresses adaptability during the short-term emergency phase and recoverability during the long-term restoration phase. The practical approach for quantifying the adaptability of a healthcare network considers changes in demand and loss of capabilities. It also considers the intricate interdependencies among building clusters, transportation systems, and hospitals, along with the complex cascading effects among both structural and nonstructural components within individual hospitals. Furthermore, the impact of various recovery strategies on resilience is thoroughly analyzed. To account for uncertainties, a Monte Carlo simulation (MCS) is integrated into the application of a real-world healthcare network located within a Chinese city. The outcomes of this study aid in identifying bottlenecks during medical rescue operations, thereby reducing casualties and assisting in decision making for postearthquake recovery efforts.
