PRAAGE: An interactive IBM-PC code for unreliability/aging analysis

Creators

Description

The more redundant a system is, the faster its unavailability increases with aging. Normally a highly redundant system has a small unavailability contribution, but aging may make it significant. This is due to the fact that, as assumed in this study, aging degradation drives up the failure rate of all redundant trains and causes a rapid loss in the effectiveness of the redundancy in reducing the unavailability. Thus aging, if allowed to cross trains, can be a significant contributor to unavailability. This conclusion demonstrates the usefulness of PRAAGE for interactive systems analysis. 3 refs., 1 fig., 1 tab
