Disaster, whether manmade or natural, can have a catastrophic impact on a populated area. Sometimes, the disaster is so devastating that it requires a large-scale evacuation. As a result, evacuation plans have become a necessity. The Illinois-Indiana-Wisconsin Regional Catastrophic Planning Team looked to improve their plan and employed A, Kirby, J.E. Dietz, E. Matson, J. Pekny, and C. Wojtalewicz from the Department of Computer and Information Technology, Purdue University, and J. Pekny from the Department of Chemical Engineering at Purdue University to do so. This project's goal was to provide data on the optimal staff, materials, space and time resources required to operate a regional hub reception center, a “short-term facility with the goal to process and transport displaced survivors (evacuees) to temporary or permanent shelters following a catastrophic incident” (Bonabeau, 2002).
