13 The ISDD Tool Suite FMECA Plus Module FTA Module Maintenance Module STAGE Run-Time Authoring Tool DSI Workbench Diagnostic Modeling and Analysis creates the models used by all tools in the ISDD tool suite. It also performs standardized analyses to help engineers optimize and assess system diagnostics/prognostics, as well as the design s ability to support effective HM. Diagnostic FMECAs The FMECA Plus module allows standard FMECA data (either imported from a commercial FMECA tool or developed within ) to be enhanced with metrics derived from the diagnostics. This module is automatically included with each license of. FTA Module The FTA Module provides a set of features that allow to create and analyze reliability fault trees. Fully integrated with both FMECA Plus and the diagnostics, this module can produce diagnostic & prognostic-informed fault trees for Reliability and Safety analysis. Maintenance Module The Maintenance Module provides a set of features that allow to support multiple levels of diagnosis. It has been designed to facilitate the concurrent development of embedded diagnostics and troubleshooting procedures (IETMs). Simulation-based Analysis Using data from, STAGE simulates failures, diagnoses and repairs that would occur in a fielded system. Calculations (represented as graphs) show changes over time, as well as the impact of maintenance upon failure. Enhancing Exported Diagnostics The Run-Time Authoring Tool (RTAT) allows diagnostic procedures exported from to be enhanced with graphic overlays and links to external documents. Diagnostics can also be reformatted for use in a variety of tools. This tool includes the Design Viewer. Run-Time Diagnostic Application DSI Workbench allows diagnostics developed in to be fielded in a maintenance or production environment. DSI Workbench supports integration with a test executive, as well as guided troubleshooting and free-form test entry.

17 Four Main Goals of Diagnostic Engineering Availability Cost of Ownership Mission Success Safety

18 Subsidiary Benefits of Diagnostic Engineering Availability Effective Isolation to Optimum Repair Level Cost of Ownership Lower MTTI / MTTR Improved MTBF Reduced False Removals Lower Maintenance Costs Improved Fault Detection Reduced False Alarms Reduced System / Mission Aborts FMECA / Fault Tree Analysis Probabilistic Risk Assessment Mission Success Unique Isolation of Critical Failures Safety

19 Contracted Diagnostic Requirements Availability Effective Isolation to Optimum Repair Level Cost of Ownership Improved Fault Detection Unique Isolation of Critical Failures Mission Success Safety

20 Fault Detection & Isolation in

21 Fault Detection in STAGE Non-Detected Failures Detected Failures

22 Fault Isolation in STAGE Isolation to Multiple LRUs Isolation to a Single LRU

23 False Alarms in STAGE Non-Alarm Faults Diagnostic False Alarms Operational (True) Alarms Isolated Diagnostic Alarms

24 System/Mission Aborts in STAGE False System/Mission Aborts True System/Mission Aborts

25 Unambiguous vs. Unique Isolation Ambiguous Isolation (Multiple Items) Item A FM-1 FM-2 Item B FM-1 FM-2 Unambiguous Isolation (Single Item) Item A FM-1 FM-2 Item B FM-1 FM-2 Unique Isolation (Root Cause(s) of Single Failure) Item A FM-1 FM-2 Item B FM-1 FM-2

26 FMECA Plus: Critical Failure Diagnosis Chart The Uniquely Isolated column indicates whether the fault group that is isolated for this failure contains only root causes of the given failure. If the fault group contains any failure modes that are not a root cause of that failure, then the failure has not been uniquely isolated by the diagnostics. The non-unique isolation of critical failures is a primary driver of false alarms and unnecessary system or mission aborts.
