The interdependencies between infrastructures may be the cause of serious problems in mission/safety critical systems. In the CRU- TIAL project the interdependencies between the electricity infrastruc- ture (EI) and the information infrastructure (II) responsible for its con- trol; maintenance and management have been thoroughly studied, more- over countermeasures to substantially reduce the risk to interrupt the service have been developed in the project. The possible interdependen- cies have been investigated by means of model at this abstraction levels. In this paper, we present high level models describing the various interde- pendencies between the EI and the II infrastructures, then we illustrate on a simple scenario how these models can be detailed to allow the eval- uation of some measures of dependability.
