A method for analyzing dysfunctions of an embedded system including a phase for modeling this system and an analysis phase, the modeling phase including defining a set of resources, a set of services, a set of statuses and at least one rule for the acquisition of a status by a resource or by a service, the analysis phase including configuring the analysis including marking a marked event and analyzing acquisition rules to determine a set of basic events and conditions for the appearance thereof, leading to the appearance of the marked basic event.

Analysis method of embedded system dysfunctions, associated computer program product and analysis device

Disclosed is an electronic apparatus for assisting an aircraft pilot. The aircraft includes avionics equipment implementing operational capacities and a monitoring system configured to determine monitoring information from operational capacities and operating parameters of the avionics equipment. The assistance apparatus includes in an acquisition module configured to acquire the monitoring information and an anomaly detection module configured to detect at least one anomaly from among a breakdown of an avionics equipment and a failure of an operational capacity, from monitoring information and anomaly detection rules contained in a predefined database. The assistance apparatus includes an inference module configured to identify, for each anomaly, one or several causes that may have caused the anomaly, based on relationships between breakdowns and failures, the relationships being contained in the database.
