A meta-model for integrating safety concerns into systems engineering processes

In order to overcome the increasing difficulty of critical systems development, integrating the safety concerns into Systems Engineering processes seems to be the relevant solution. This paper proposes a meta-model to perform this integration by considering phased mission systems composed of repairable components. This kind of system requires in particular that several redundancy policies be defined. The benefits of this contribution are illustrated on a small example from the domain of electric power production.
