Abstract : The diagnosis is today more than ever a relevant research topic. Safety is indeed in the heart of the concerns of the company of today. Stakes as well economic, environmental as at the society level, do of the diagnosis one of the major axes of innovation for current industry. Today the design and the exploitation of the systems must be approached by integrating a safety dimension of which the diagnosis forms integral part. It is in this problematic of diagnosis (including detection and prognosis) that our work is registered. Two research topics are explored: - models and sources of knowledge for the diagnosis. This research topic covers the multi-models aspects (process model, monitoring model, model of strategy...) for the monitoring, and emphasizes the use of varied information sources (scheduling, AMDE, histories...) to design a diagnosis function. The generation of a behavioural model from classified data is also considered in this topic. A monitoring approach based on the trajectory observation of a dynamic system through a sequence of classes to which the current state belongs is developed. - the distributed diagnosis. The suggested approaches are focused on the distribution of the functions and the models. An approach of distributed detection based on a time model (constraints) of the awaited behaviour is developed. An extension towards the embedded diagnosis in the automotive field based on a behavioural model issued from design data is also presented. On the basis of this work our research project relates to on one hand the use of date based approaches to structure knowledge and to automatically generate exploitable models by model based methods of diagnosis, on the other hand the problem of the diagnosis for the decision-making aid, notably in systems where human dimension must be considered
