Reconstruct multi-level territory dynamics with complex networks and self-organizing multi-agent systems

Cyrille Bertelle (University of Le Havre, France)

The paper will present one of the first possible applications of TIMES. One of the main characteristics of complexity is the emergence of properties due to dynamical processes. Our objective is to contribute to the formalization of these emergent properties studying dynamical structures. The structures of complexity proposed here, are interaction systems as the core of self-organization mechanisms. Dynamical networks are efficient tools to express some local or global properties of evolving topology. They capture structural aspects of complex systems representing entities as nodes and interactions between them as links. This contribution presents adaptive algorithms for complex networks dynamics, leading to identify emergent organizations in these networks. One of this algorithms, named AntCo2, is bio-inspired by social insect system behavior and lead to detect emergent structures inside complex networks. Some applications are presented relating to urban morphodynamics analysis of the communication networks of the city. Practical study cases are developed (i) to analyze network vulnerability in case of urban technological risk, using multi-scale measures on dynamical complex systems and (ii) to reconstruct the complexity of logistic corridors as interface between port and metropolitan systems.  The simulations and results detailed in this presentation, are powered by the GraphStream Library which is a java package for dynamic complex networks (
