Multi-level Dependability Modeling of Interdependencies between the Electricity and Information Infrastructures

The interdependencies between infrastructures may be the cause of serious problems in mission/safety critical systems. In the CRUTIAL3 project the interdependencies between the electricity infrastructure (EI) and the information infrastructure (II) responsible for its control, maintenance and management have been thoroughly studied; moreover countermeasures to substantially reduce the risk to interrupt the service have been developed in the project. The possible interdependene been investigated by means of model at different abstraction levels. In this paper, we present high level models describing the various interdependencies between the EI and the II infrastructures, then we illustrate on a simple scenario how these models can be detailed to allow the evaluation of some measures of dependability.
