This paper deals with the modelling and evaluation of mission-phased systems devoted to space applications. We propose a two level hierarchical method that allows to model such systems and to master the complexity of the analysis. Our approach considers a separate modelling and resolution of the phases, and of the dependencies among phases caused by the(More)
This paper describes the dependability modelling and evaluation of a real complex system, made of redundant replicated hardware and redundant diverse software. It takes into account all aspects of their interactions (including correlation between the diverse software variants) and of the criticality of the several components. Our approach has been to(More)
