This paper deals with the use of Bayesian Networks to compute system reliability of complex systems under epistemic uncertainty. In the context of incompleteness of reliability data and inconsistencies between the reliability model and the system modeled, the evidence theory is more suitable to manage this epistemic uncertainty. We propose to adapt the(More)
The design of modern embedded systems becomes more complex every day, due to the increasing amount of components and distinct functionalities incorporated into a single system. To address this situation, projects' abstraction level is continuously raised. In addition, techniques to speed up the code production process have emerged. These new trends lead to(More)
Proactivity in maintenance, which is mainly materialized by degradation-based anticipation, becomes essential to avoid failure situation with negative impact on product and/or system conditions. It leads to make emerging the E-maintenance philosophy to move from “fail and fix” maintenance practices to “predict and prevent” strategies. Within these new(More)
At present we can find different complementary definitions of the term e-Maintenance. These definitions apply to maintenance several principles and concepts such as collaboration, pro-activity, knowledge, intelligence, web services or the Internet. A clear consensus is not yet reached, even when some contributions try to propose unique repositories to(More)
Nowadays, the risk analysis of critical systems cannot be focused only on a technical dimension. Indeed last well known accidents in nuclear or aerospace areas underlined initiating causes also related to technical and organisational viewpoints. It led to the development of methods for risk assessment considering three main aspects on the system resources:(More)
