EXFAULT

EXFAULT is a general purpose Abacus expert system to perform fault diagnosis on a wide range of electrical, electromechanical, and mechanical systems involving cause/effect relationships.  For such systems, EXFAULT replaces procedures manuals usually used in fault diagnosis and enables an unsophisticated user to perform the testing.  EXFAULT advises the user of tests to perform and the proper sequence of the tests to isolate the faulty component.  It optimizes the test procedure, isolating the fault with a minimum number of tests.  To enhance user-friendliness, EXFAULT can be integrated with interactive video disk systems (see ETSS) and, through computer selected video images, can show the user explicitly how to perform the required tests.

Expertise for the system is generated directly from CAD schematic diagrams with occasional input, where necessary, from lab results.  The system also allows for storing a history of test results so that diagnosis procedures can be changed to deal with items that fail more frequently.  A key feature of EXFAULT is that it can be used in the systems design process in simulation mode, enabling a design engineer to optimize for total life cycle costs taking into account development as well as maintenance.

EXFAULT can also be used to drive automated testing procedures, eliminating significant amounts of ATE programming normally needed in automated test environments.  It can be integrated with any conventional system.
