Reliability Inversion: A Cautionary Tale

Reliability Inversion: A Cautionary Tale

Reliability analysis is often based on worst-case assumptions to produce guaranteed lower bounds on system survival probability. Reliability engineers make lower bounds as tight as possible, but sometimes system structure is unfriendly to the derivation of tight bounds. Unfortunately, loose reliabil...

Zusammenfassung:Reliability analysis is often based on worst-case assumptions to produce guaranteed lower bounds on system survival probability. Reliability engineers make lower bounds as tight as possible, but sometimes system structure is unfriendly to the derivation of tight bounds. Unfortunately, loose reliability lower bounds make it difficult to compare design alternatives or to select among competing systems.
