ABS4 will be held in Montpellier, France, from 28 to 30 april 2003. This workshop is intended to offer a forum for people interested in agent-based simulation to discuss methodologies, techniques and applications. We encourage contributions that present not only case studies but also critical analysis on the pertinence of multi-agent models and their usefulness for understanding or for decision making, design and validation methodologies, comparative studies in the modelling sciences. In particular, the subjects include but are not limited to: - Design, implementation and validation methodologies, including participative protocols; - Modelling languages and platforms; - Agent architecture either for biophysical or for social simulations; - Interaction protocols including with humans; - Multi-level simulation and emergence of global phenomena (including norms and institutions); - Time and space representation including multiple scales; - Comparison with centralized models, relationship between individual-based versus aggregative models; - Conceptual and epistemological analysis. The application domains include but are not limited to: - Ecology and environment; - Psychology and cognitive science; - Social simulation; - Economical models; - Industry, manufacturing and logistics; - Robotics; - Virtual reality.
