Abstract :
The concepts of accuracy and resolution of a diagnostic procedure are introduced. Both measures can be computed using diagnostic data obtained from the fault simulation process and used as figures of merit for the diagnostics applied to the system. With these measures, the designer is able to evaluate his diagnostic program design and dictionary or catalog techniques prior to the actual field implementation. The results obtained by applying these measures to the Bell System´s No. 1 Electronic Switching System are also discussed.
