eXpress is a software suite of diagnostic
engineering tools that encompass diagnostics, testability, prognostics and
systems engineering and represents the result of over 30 years of
software development. It provides enormous short and long-term cost-savings,
realized throughout the entire life cycle.
eXpress provides the capability to capture
design information from a systems perspective and may be used to seamlessly
combine disparate sources of data. eXpress couples the Systems Engineering, Reliability, Testability, Maintainability and
Diagnostic/Testability disciplines. This provides a true end-to-end solution, which
can begin as early as concept exploration, and carries through run-time
deployment and beyond.
eXpress' approach handles system-level
design capture and analysis across large engineering teams. By providing
the most in-depth Testability and Diagnostics assessment capabilities on the
market today, eXpress can
tackle tasks ranging from the smallest embedded component to entire aircraft
Features of eXpress
eXpress can be used to capture the design of both new and legacy designs and provides
support for multi-discipline designs. These include electrical/electronic, mechanical,
hydraulic and other systems. The express software is fully scalable and can
deal with large systems design in additional to smaller systems.
Testing and Diagnostics
Strategy optimization is achieved by focusing on the overall “diagnosability”
of a system or device during development. Engineering changes are always a
trade-off that adds good behaviour at the expense of some bad behaviour.
eXpress provides the tools to help determine whether and how these changes
should be made.
Reliability Engineering Support
The reliability module adds an additional layer to the eXpress model. It allows
failure modes to be tracked throughout the entire system design in terms of
their effects on the system. From this information, a FMECA report is easily
Health Management Framework
eXpress is ideally suited for Vehicle
Health Management development. As a system tool, eXpress easily handles either Integrated Vehicle Health
Management (IVHM). Integrated System Health Management (ISHM) or Integrated
Prognostic Health Management (IPHM). The later term referring to the bigger
picture where IVHM technologies have moved to a systems level, that includes
ground support, remote monitoring and management, etc.
Support of Maintainability
supports much more than just Testability and Diagnostics assessment. The
eXpress model also provides the knowledge to support maintainability studies. Simulation-based
statistics bring many simple Testability statistics into the Life Cycle Cost
domain needed to support prognostics design and maintainability studies.
Validation and Verification
eXpress' solution to the validation problem is multi-faceted. The change process
is done through an integrated error-checker. This helps notify of any
definition problems before time is wasted solving problems that show up on
dependent layers of information. The provision of extensive reporting allows
data drill-down into any aspect of the design.
