Evaluating the Performance of Iterative Proportional Fitting for Spatial Microsimulation: New Tests for an Established Technique

Lovelace, Robin; Birkin, Mark; Ballas, Dimitris; … - In: Journal of Artificial Societies and Social Simulation 18 (2015) 2, pp. 21-21

Iterative Proportional Fitting (IPF), also known as biproportional fitting, â€˜rakingâ€™ or the RAS algorithm, is an established procedure used in a variety of applications across the social sciences. Primary amongst these for urban modelling has been its use in static spatial...

Bibliometrics, Stylized Facts and the Way Ahead: How to Build Good Social Simulation Models of Science?

Meyer, Matthias - In: Journal of Artificial Societies and Social Simulation 14 (2011) 4, pp. 4-4

This paper discusses how stylized facts derived from bibliometric studies can be used to build social simulation models of science. Based on a list of six stylized facts of science it illustrates how they can be brought into play to consolidate and direct research. Moreover, it discusses...

Pitfalls in Spatial Modelling of Ethnocentrism: A Simulation Analysis of the Model of Hammond and Axelrod

Jansson, Fredrik - In: Journal of Artificial Societies and Social Simulation 16 (2013) 3, pp. 2-2

Ethnocentrism refers to the tendency to behave differently towards strangers based only on whether they belong to the ingroup or the outgroup. It is a widespread phenomenon that can be triggered by arbitrary cues, but the origins of which is not clearly understood. In a recent simulation model...

A Common Protocol for Agent-Based Social Simulation

Richiardi, Matteo; Leombruni, Roberto; Saam, Nicole J.; … - In: Journal of Artificial Societies and Social Simulation 9 (2006) 1, pp. 15-15

Traditional (i.e. analytical) modelling practices in the social sciences rely on a very well established, although implicit, methodological protocol, both with respect to the way models are presented and to the kinds of analysis that are performed. Unfortunately, computer-simulated models often...

Design Versus Cognition: the Interaction of Agent Cognition and Organizational Design on Organizational Performance

Carley, Kathleen M; Prietula, Michael J.; Zhiang (John) Lin - In: Journal of Artificial Societies and Social Simulation 1 (1998) 3, pp. 4-4

The performance of organizations with different structures are examined using multiple computer simulation models, experimental data, and archival data focused on the relation between the way in which the organization is coordinated and its performance. These variations enable the exploration of...
