Agent Based Models ( Abm ) - 2005 Words

Agents Based Models (ABM) - Introduction to ABM A model is a representation of a real system and thus, it is an abstraction of the reality 4. â€Å"The word â€Å"modeling† comes from the Latin word modellus which describes a typical human way of coping with the reality† (Schichl, n.d.). Models can take various forms such as mathematical equation, drawing, computer code, etc. However, there is a common purpose of all designed models, which is to simplify the complexity presented in the real system or problem. Therefore, models usually contain only the main aspects of the real system (not all details). Macal and North (2006) believe that ‘‘There is no universal agreement on the precise definition of the term ‘agent’, although definitions tend to agree on more points than they disagree’’. It seems very complicated to extract agent characteristics from the literature in a consistent and constant perspective, because they are utilised in different ways (Bonabeau 2002). Agent-based modelling (ABM) is able to simulate the individual activities by measuring their behaviour and results over time for developing models of cities (Crooks 2006). Agent-based modeling and simulation (ABMS) is a new approach to modeling systems comprised of autonomous, interacting agents. Agent-based modeling is a new analytical method for the social sciences, but one that is quickly becoming popular. ABMS promises to have far-reaching effects on the way that businesses use computers to support decision-making andShow MoreRelatedAgent Based Models ( Abm )2001 Words   |  9 PagesAgents Based Models (ABM) A model is a representation of a real system and thus, it is an abstraction of the reality 4. â€Å"The word â€Å"modeling† comes from the Latin word modellus which describes a typical human way of coping with the reality† (Schichl, n.d.).

Macal Michael J. North *NetLogo is a free ABMS environment (Wilensky 1999) developed at Northwestern University’s Center for Connected Learning and Computer-Based Modeling (http://ccl.northwestern.edu/netlogo/). The NetLogo language uses a modified version of the Logo programming language (Harvey 1997). NetLogo is designed to provide a basic computational laboratory for teaching complex adaptive systems concepts. NetLogo was originallyRead MoreCombating Threat From Social Engineering1137 Words   |  5 Pagesnever taught . Agent Based Research Some of the most interesting and newest research into social engineering was first proposed by Stephanie White in 2003 and involves an agent based system. This idea of fitting people, or agents, into models is an idea, which is catching on. This idea ties a process or a role to each individual agent or team to produce what Ms. White calls an â€Å"artifact† or simply a result . Argonne National Laboratory recently won a large grant to build an Agent Based Modeling andRead MoreWhat Is The Potential Damages Of Future Climate Change Impact Of Flooding Risk1037 Words   |  5 PagesEvaluated potential damages of future climate change impact of flooding risk by empirical method based and relies on statistical relationships between historical precipitation and flood damage.
