![]() Some examples are reviewed in section three. Agent-based modeling has been used successfully to model complex adaptive systems in many disciplines, including archaeology, biology, ecology, supply chains, consumer market analysis, military planning, and economics (North and Macal 2007 North and Macal 2009). By modeling these agents individually, the full effects of the diversity that exists among agents with respect to their attributes and behaviors can be observed as they give rise to the dynamic behavior of the system as a whole.Īgent-based modeling provides a mechanism for modeling CASs (Bonabeau 2002 Macal and North 2010). They interact with and influence each other, learn from their experiences, and adapt their behaviors so they are better suited to their environment(s). CAS agents have properties and behaviors. We discuss opportunities for future work, including plans to provide support for increasingly large-scale modeling efforts.Ĭomplex adaptive systems (CASs) are composed of interacting, autonomous agents (Holland 2006). Include a review of several Repast Simphony applications and brief tutorial on how to use Repast Simphony to model a simple complex adaptive system. The architectural description includes a discussion of the Simphony application framework, the core module, ReLogo, data collection, the geographical information system, visualization, freeze drying, and third party application integration. Includes reviewing other free and open-source modeling libraries and environments as well as describing the architecture of Repast Simphony. ![]() The Repast family of agent-based modeling software has collectively been under continuous development for more than 10 years. ![]() The resulting code has a modular architecture that allows individual components such as networks, logging, and time scheduling to be replaced as needed. Repast Simphony was designed from the ground up with a focus on well-factored abstractions. This paper is to describe development of the features and functions of Repast Simphony, the widely used, free, and open source agent-based modeling environment that builds on the Repast 3 library. ![]()
