Risk Quadruplet: Integrating Assessments Of Threat, Vulnerability, Consequence, And Perception For Homeland Security And Homeland Defense, Kara Norman Hill
Risk Quadruplet: Integrating Assessments Of Threat, Vulnerability, Consequence, And Perception For Homeland Security And Homeland Defense, Kara Norman Hill
Engineering Management & Systems Engineering Theses & Dissertations
Risk for homeland security and homeland defense is often considered to be a function of threat, vulnerability, and consequence. But what is that function? And are we defining and measuring these terms consistently? Threat, vulnerability, and consequence assessments are conducted, often separately, and data from one assessment could be drastically different from that of another due to inconsistent definitions of terms and measurements, differing data collection methods, or varying data sources. It has also long been a challenge to integrate these three disparate assessments to establish an overall picture of risk to a given asset. Further, many agencies conduct these …
Simulation-Based Evaluation Of Port Evacuation Plans For Predictable Natural Disasters, Xiuli Qu, Maurice Jackson, Lauren Davis
Simulation-Based Evaluation Of Port Evacuation Plans For Predictable Natural Disasters, Xiuli Qu, Maurice Jackson, Lauren Davis
Dr. Lauren B Davis
Effective port emergency evacuation could reduce the potential damages and losses caused by a predictive natural disaster. Thus, most U.S. ports have evacuation plans or guidelines established for predictive natural disasters, especially hurricanes. However, hurricane Katrina still revealed that these existing emergency evacuation plans may not be as effective as originally expected. The objective of this study is to provide a quantitative approach to evaluating the effectiveness of port emergency evacuation plans for hurricanes. A discrete-event simulation model is developed in this study to capture the dynamic evacuation process in a complex port environment when a hurricane approaches a port. …
