Abstract : This thesis deals with the diagnosis of behavior functions in the embedded network systems and especially in the automotive systems. It is focused on the localization of intermittent faults in discrete events systems. The proposed methods are based on a discrete events model representing the normal functioning of the observable behavior of the monitored system. The detection step consists of a comparison between the flow of observable events emitted by the monitored system and the flow foreseen by the model. A localization mechanism, based on the diagnoser approach (Sampath et al., 1998), points out the set of events potentially responsible for the faults. The aim of this approach is to get the diagnosis information into a data structure (off-line) which efficiently joins the observations with the faults during the on-line diagnosis. This thesis have lead to the building of many applications for the intermittent fault diagnosis. This works have been validated on a test bench representing the network used in the city transports (bus, subways...).
