“…Applications range from modelling agent behaviour in the stock market (Arthur et al, 1997) and supply chains (Macal, 2004a) to predicting the spread of epidemics (Bagni et al, 2002) and the threat of bio-warfare (Carley et al, 2006), from modelling the adaptive immune system (Folcik et al, 2007) to understanding consumer purchasing behaviour (North et al, 2009), from understanding the fall of ancient civilizations (Kohler et al, 2005) to modelling the engagement of forces on the battlefield (Moffat et al, 2006) or at sea (Hill et al, 2006), and many others. Some of these applications are small but elegant models, which include only the essential details of a system, and are aimed at developing insights into a social process or behaviour.…”
