ABSTRACT

81

Natural or human-made incidents in urban areas cause surges in demand for hospitals while oftentimes simultaneously limiting their capacity to serve patients due to direct physical damage or service interruptions in supporting lifelines. A hierarchical modeling concept is proposed to quantify resilience of regional hospital response under disaster. To facilitate the optimization of pre- and post-event resilience enhancing actions for a range of potential hazard-demand-damage scenarios, a multi-stage stochastic, mixed integer decision problem (SMIP) is proposed. Dependencies on interdependent, potentially damaged critical lifelines are explicitly modeled. Resilience is estimated in terms of total patient waiting time and unserved patients. These quantities are captured in the objective of the SMIP through the adoption of a simulation-based metamodel of a detailed hospital model. The SMIP is demonstrated on a numerical example developed to represent the main hospitals of the Johns Hopkins Health System coalition. The proposed structure is broadly applicable to other societal functions that take place in interrelated buildings connected by transportation and communications links and are dependent on interdependent lifeline networks.
