Un processus de développement en spirale pour la simulation multi-agents

The general framework of our project is the development of a simulation environment for complex systems with an agent-based approach. The main goal is to define and implement an evolutionary and generic platform. This paper describes an application of our research in this area, by presenting a development process adapted to this kind of issue. Because of the non-determinist part of the tackled domain, and the agent-approach which is yet in its infancy, a spiral-based methodology seems the appropriate solution to successfully tackle this issue. On the other way, implementing such applications needs a well-suited environment. In such a frame, Smalltalk and uppers levels which have been developed on the top was a very interesting candidate to investigate, as it offers a wide variety of common mechanisms to build both agents and simulation tools.
