Reliability databases: principles and construction

Abstract

International audienceTo facilitate users search for information on systems or components and surveys of historical data (design, test results and failures of components, date and duration of system maintenance,...) for dependability needs, data are stored in data banks or databases. These needs are of several types: availability and logistics needs of military equipment and the need for safety in hazardous industries, designers, manufacturers and managers responsible for installations, etc. This paper presents the basic concepts which guide the construction of a reliability database. For this purpose, the principal definitions related to reliability data as well as the principal methods used for reliability data collection, are given. Finally, some of the best-known databases are presented, followed by the principles of database management systems
