Agnes Kotucz (BMW Group, München): Empirische Assoziationsanalyse mit dem Ziel eines Wissensaufbaus für Fehler-Ursachen-Beziehungen in elektronischen Systemen mit Netzwerkarchitektur.

The increasing rate of electronics and distributed functions in electrical appliances is providing the necessary for detection of component degradations and isolations the root causes of failures. The data-driven approach consists of data from the on-board diagnosis, the DTCs, and concomitant warranty data, like labor codes from repair cases. The presentation discusses a modified association analysis for fault analysis. It includes aspects of rule significance, redundancy and causality. Furthermore we show a possibility to use association analysis in a supervised way for target items.
