Identifying Geographical Interdependency In Critical Infrastructure Systems Using Open Source Geospatial Data In Order To Model Restoration Strategies In The Aftermath Of A Large-Scale Disaster, Varun Ramachandran, Tom Shoberg, Suzanna Long, Steven Corns, Hector Carlo Jul 2015

Identifying Geographical Interdependency In Critical Infrastructure Systems Using Open Source Geospatial Data In Order To Model Restoration Strategies In The Aftermath Of A Large-Scale Disaster, Varun Ramachandran, Tom Shoberg, Suzanna Long, Steven Corns, Hector Carlo

International Journal of Geospatial and Environmental Research

In the wake of a large-scale disaster, strategies for emergency search and rescue, short-term recovery and medium- to long-term restoration are needed. While considerable effort is geared to developing strategies for the former two options, little comprehensive guidance exists on the latter. However, medium- to long-term restoration has a significant effect on local, regional and national economies and is essential to community vitality. In part, the deficit of robust strategies can be linked to the complexity in the data acquisition and limited methodologies to understand the interconnectedness of the relevant systems elements. This research utilizes infrastructure data for Supply Chain …


Assessing Survivability Of The Beijing Subway System, Yan Li, Hyun Kim Jun 2014

Assessing Survivability Of The Beijing Subway System, Yan Li, Hyun Kim

International Journal of Geospatial and Environmental Research

The Beijing subway system, the third largest in the world, serves more than ten million passengers a day. As Beijing is the capital city of China and thus a booming urban center, its subway system has experienced rapid evolution from a local single line system to a complicated network. Due to its constantly increasing complexity, the system is both a critical asset for a local transit artery and a bridge between intercity transportation modes, increasing the issue of network survivability in the face of potential outages of network components. In this study, we provide a connectivity-based survivability measure with which …
