In den Proceedings zur 5. Internationalen GI/ITG/GMA-Tagung }ber Fehlerorientierte Rechensysteme in N}rnberg standen Tests, Diagnose und Fehlerbehandlung als Leitthemen im Mittelpunkt. Allerdings wurden auch die Themen Zuverl{ssigkeit, Verf}gbarkeit und Sicherheit in Hard- und Softwaresystemen behandelt. Der Tagungsband gibt mit eingeladenen und eingereichten Beitr{gen, die von einem internationalen Programmausschu~ sorgf{ltig ausgew{hlt wurden, eine ]bersicht }ber den Stand der Forschung, Entwicklung und Anwendungen aller Fehlertoleranz- und Zuverl{ssigkeitsaspekte.
