What if you wanted to model the spread of say a disease across the current world population of 6.7 billion people? Think it can be done? It can, by the Large-Scale Agent Model, which resides at the Brookings Institution's Center on Social and Economic Dynamics. It was developed with guidance of the Homeland Security Department's National Center for the Study of Preparedness and Catastrophic Event Response at Johns Hopkins University.
The cool part: the model includes factors like age and gender and how individuals are dispersed geographically. It even models the daily commute! Check out video of it in action in a
GovExec article. They show the spread of a disease and a toxic release. (Those seem to be favorites these days).
