Epidemic modeling has been used in mapping epidemics since the 1920s. But in order to catch up to the times, new modeling techniques need to be utilized. Agent-based models (ABMs) are suited for today’s complex social networks. The agents are tracked and can be programmed to behave like real people. SFI External Professor Joshua Epstein is one of the scientists using the new Global-Scale Agent Model (GSAM) which was developed at the Brookings Institution’s Center on Social and Economic Dynamics. This model has 6.5 billion agents that can be tracked. The GSAM has been presented to the Center for Disease Control and Prevention. With the pandemic of H1N1 and other diseases, agent-based modeling will play an integral part in assisting authorities to track possible outcomes and solutions.
