Common cause failures (ccf), Advanced Statistics

Assignment Help:

Common cause failures (CCF): Simultaneous failures of the number of components due to a same reason. A reason can be external to the components, or it can be the single failure which propagates to other components in the cascade. Even if such events are rare compared to the single failures of the component, they can dominate the system unreliability or unavailability. A number of models for predicting CCFs have been recommended.
