System operators, maintainers and
managers need to know the current and anticipated status of
their systems and equipment, and whether the system will be
able to perform its various functions and remain operational.
VSE's core technology is an
expert system using model based reasoning that uses a
design-based model for diagnostics and prognostics. It is a
deterministic approach that uses "first principles" of design.
The reasoner dynamically interprets input data to detect and
anticipate faults, and to isolate faults to the repair item.
