Besides the new concepts which lead us to question older concepts (risk, hazard and vulnerability), we propose to think about more practical aspects, for example the modelling of human behaviour and the confrontation in crisis situations. The link between concepts as: critical self-organization, emergence, bifurcation, and the methods in the Distributed Artificial Intelligence used to model them is however difficult. In this paper, we present ongoing analysis on the key concepts of risk science, such as the hazards and the catastrophes. We propose to enrich them with complex sys-tems theories. First, we present methodological perspectives ...
