Block Replacementis an approach to maintaining a system in which all items that have been isolated by diagnostics (i.e., all items in an isolated fault group) are replaced together as a block prior to additional tests being performed. Block Replacementis the maintenance strategy most often assumed when assessing the diagnostic capability of device and therefore forms the basis of the most commonly used fault isolation metrics. Compare with Serial Replacement
Probability of Isolating Items in Category to Fault Group of Size 1 Using Only Testing
Subset FD/FI Statistics Report
In the eXpressFault Isolation Report, metrics based on Block Replacementare included in the category Isolation Probabilities Using Testing Only. In the Subset FD/FI Statistics Report, Block Replacementis assumed when calculating the Probability of Isolating Items in Category to Fault Group of Size 1 Using Only Testing.
