MODIFIED, COMPLEMENTED TAXONOMY OF FAULTS IN FAULT-TOLERANT REAL-TIME SYSTEMS

Abstract

This paper presents the main definitions relating to dependability. Basic definitions including reliability, security, maintainability, etc. are described first. They are then supplemented by additional definitions, which address to the threats of dependability (faults, errors, failures). Overlapping dependability standards, renumbering and integration can cause uncertainty when using of a certain definition. For this purpose, authors present complemented fault taxonomy for fault-tolerant real-time systems to eliminate inconsistencies and to unify existing fault taxonomies.
