Читать книгу System Reliability Theory - Marvin Rausand - Страница 29

Availability measures the degree to which an item is able to operate at some future time or during a future time interval , and is in this book regarded as a reliability metric. The availability of an item depends on the reliability, recoverability, and maintainability of the item, and also on the maintenance support performance. Recoverability is the item's ability to recover from a failure, without repair. Maintenance support is the resources that are available for maintenance, such as workshops, qualified personnel, and tools. Availability is discussed in Chapters 6, 11, and 13.
