1. A fault diagnostic system for a unit under test, characterized by:

  • a plurality of model data bases for modeling and providing unit under test behavior data including first model data bases for modeling and providing unit under test parts connectivity data, second model data bases for modeling and providing unit under test parts attributes data, and third model data bases for modeling and providing unit under test behavior, failure modes and effects analysis, and functional data;

    means bidirectionally connected to the plurality of model data bases for receiving the data therefrom and for converting the received data into a predetermined context and format, and for transmitting the converted data to the plurality of model data bases;

    a model bididrectionally connected to the converting means and receiving the converted data therefrom for modeling and providing failure modes and effects analysis data and for transmitting said data to the converting means;

    means bidirectionally connected to the converting means and to the failure modes and effects analysis data means and receiving the converted data and the failure modes and effects analysis data for providing modifying data, and for transmitting the modifying data to the converting means and to the failure modes and effects analysis data means; and

    means bidirectionally connected to the converting means and to the modifying data means and receiving the converted data and the modifying data for modeling both good and faulty performance of the unit under test and for providing corresponding data, and for transmitting the corresponding data to the converting means and to the modifying data means.
