Abstract

The work presented in this paper is devoted to the definition of a dependability modelling approach for the selection process of instrumentation and control systems (I&C) in power plants. We show how starting from functional specifications, a functional-level model can be transformed into a dependability model taking into account the system's architecture, following a progressive and hierarchical approach. This approach is illustrated on simple examples related to a specific architecture of an I&C system.
