Contribution to system of systems modeling

Abstract

Modeling a system of systems, for supervision purpose, is a complex issue influenced by security constraints more important than those of its component systems. This work proposes a hierarchical model of system of systems based on Hypergraphs and Constraint Satisfaction Problems. First of all, the developed model allows the operator to show, by a bottom up analysis of the hyper-graphs, the failure of a local system, and its influence on the other systems. In the other hand, the top down analysis of the hypergraphs, allows to check the possible reconfigurations of the global system of systems that satisfy a maximum number of constraints.
