Abstract
A method for enabling a diagnostic system to assess, within time constraints, the health of the host system during operation, and to detect and isolate system faults during maintenance, with reduced potential for false alarms due to intermittent real faults and system noise, and for apparent misdiagnosis of the host system health, by use of a Diagnostics by Confidence Measure Assessment (DCMA) process in which a confidence measure is provided for each system test failure assessment, resulting from both the use of specialized persistence processing on many test results from a single source and the use of specialized corroboration processing on many test results from different sources.
