A better understanding of multi-level systems is essential for future ICT’s and for improving life quality and security in an increasingly interconnected and interdependent world. Indeed, multi-level dependencies may amplify cascade failures or make more sudden the collapse of the entire system. Recent large-scale blackouts resulting from cascades in the power-grid coupled to the control communication system witness this point very clearly.

Complex networks science is particularly suited to shed new light on the structural and dynamical interrelations between infrastructure and communication networks and between techno-social and socio-economic networks. MULTIPLEX proposes a mathematical, computational and algorithmic framework for multi-level complex networks. Firstly, this will lead to a significant progress in the understanding and the prediction of complex multi-level systems. Secondly, it will enable a better control, and optimization of their dynamics. Combining these modelling approaches with the analysis of massive heterogeneous data sets will lead to profound insights into the topology, dynamical organization and evolution of multi-level complex networks.
