Abstract : This study takes place in the field of system health management, which aims at developing maintenance aid tools, but also at improving the systems autonomous decision-making in case of failures. In this context, diagnostic techniques determine whether and why the system is down, while prognostic techniques determine when failures will occur and their consequences. If they seem to be correlated, they are usually studied separately because the time scales manipulated by the two processes are very different. This work aims at developing a tool that integrates both diagnosis and prognosis methods for the monitoring of hybrid systems, whose dynamics are both continuous and discrete. The proposed methodology, based on hybrid particle Petri nets, is applied to a planetary rover to demonstrate its usability in real cases through the management of knowledge-based and data-based uncertainty
