eXpress Diagnostic Deployment to the IETM

Report
The ISDD Tool Suite
eXpress
Diagnostic Modeling and Analysis
eXpress 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.
eXpress
FMECA Plus
Module
Diagnostic FMECAs
The eXpress FMECA Plus module allows standard FMECA data (either imported from a
commercial FMECA tool or developed within eXpress) to be enhanced with metrics derived from
the eXpress diagnostics.
eXpress
Maintenance
Module
eXpress Maintenance Module
The eXpress Maintenance Module provides a set of features that allow eXpress to support
multiple levels of diagnosis. It has been designed to facilitate the concurrent development of
embedded diagnostics and troubleshooting procedures (IETMs).

Run-Time
Authoring Tool
Enhancing Exported Diagnostics
The eXpress Run-Time Authoring Tool (RTAT) allows diagnostic procedures exported from
eXpress to be enhanced with graphic overlays and links to external documents. Diagnostics can
also be reformatted for use in a variety of tools.
DSI
Workbench
Run-Time Diagnostic Application
DSI Workbench allows diagnostics developed in eXpress 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.

Benefits of using the DSI Workbench
History & Feedback Module
• Fully-Integrated Database – automatically stores information about
work orders, diagnostic sessions, test results, diagnosed failures, corrective
actions, repair times, etc. As data accumulates, it can be used for various
applications, including trend analysis, design/process improvement,
efficiency evaluation, or logistics planning.
• Built-In Report Generator – allows you to quickly create useful graphs
showing information such as Ticket Resolutions, Ticket Times, Open
Tickets or Rework Cycles. Data can presented side by side for different
UUTs, repair items, User IDs or specified date intervals. Data can also be
categorized by user-defined resolution type (manufacturing defect,
component failure, documentation error, etc.)
• Historical Resolutions – provides heuristics within DSI Workbench so
that empirical knowledge derived from the maintenance history can be used
to supplement the model-based diagnostics from eXpress.

Two Types of Diagnostics Available in
DSI Workbench
• Model-Based Diagnostics – The Primary Suspects panel lists all
currently suspected items (with specific functions or failure modes).
Model-based diagnostics, because they are based on engineering data for the entire
design, are particularly good at identifying uncommon or first-time failures and will
have been fine-tuned to identify critical failures.
• Empirical Diagnostics – The Resolution History panel lists past
solutions that are consistent with the current test results.
Empirical diagnostics, because they are based on previous successes—as identified
by technicians—are particularly good at identifying issues fall outside the scope of
engineering (such as manufacturing defects, test station failures, inadequate or
missing documentation, etc.).
