ISDD Tool Suite

The Integrated System Diagnostic Design or ISDD Tool Suite provides a start to finish solution for meeting all the diagnostic needs of system design. The ISDD design process is centered around functional modeling of systems which is used to develop the diagnostics and failure analysis necessary to influence and fully support effective integrated systems design. This includes:

ISDD Tool Suite

  • Analysis of Fault Detection and Fault Isolation.
  • Interoperability and reuse of interdisciplinary-produced design data
  • Analysis of critical failures and their impact upon safety.
  • Detecting and reducing false alarms caused by diagnostics.
  • The impact of prognostics upon fault detection/fault isolation and mitigation of critical failures.
  • Development of vehicle health management and troubleshooting diagnostics
