Fides (latin: ''trust'') is a guide allowing estimated reliability calculation for electronic components and systems. The reliability prediction is generally expressed in FIT (number of failures for 109 hours) or MTBF (Mean Time Between Failures). This guide provides reliability data for RAMS (Reliability, Availability, Maintainability, Safety) studies. ==Purpose== Fides is a ''DGA'' (French armament industry supervision agency) study conducted by a European consortium formed by eight industrialists from the fields of aeronautics and Defence: *AIRBUS France *Eurocopter *Nexter Electronics *MBDA Missiles Systems *Thales Services *Thales Airborne Systems *Thales Avionics *Thales Underwater Systems The first aim of the Fides project was to develop a new reliability assessment method for electronic components which takes into consideration COTS (commercial off-the-shelf) and specific parts and the new technologies. The global aim is to find a replacement to the worldwide reference MIL-HDBK-217F, which is old and has not been revised since 1995 (issue F notice 2). Moreover, the MIL HDBK 217F is very pessimistic for COTS components which are more and more widely used in military and aerospace systems. The second aim was to write a reliability engineering guide in order to provide engineering process and tools to improve reliability in the development of new electronic systems. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fides (reliability)」の詳細全文を読む スポンサード リンク
