Description:This text brings together differing geographic perspectives in modeling and analysis in order to highlight infrastructure weaknesses or plan for their protection. International scholars, from a variety of disciplines — geography, regional science, planning, public policy, operations research, mathematics, computer science, engineering and transportation, offer varying perspectives on this subject. This text is an important contribution offering synthesis and new methodological approaches. The purpose of this volume is to explore the potential consequences of critical infrastructure failure, stemming from both man-made (e.g., terrorist attacks) and natural disasters (earthquakes, hurricanes, etc.). The approaches employed are wide-ranging, including geographic, economic and social perspectives on critical infrastructure issues.
