Abstract

Apparatus and a method for providing a micro-computer based expert system having a knowledge base of failure analysis, as it pertains to metallic components. The apparatus and method includes interactive initialization procedure which includes communications between the user and the knowledge base. The system and method incorporates automated visual aids for the analysis of metal failure.

Claims

1. A digital processing system with expert system part failure analysis, said system comprising

a digital data processing device;

data storage means in electrical communication with said digital data processing device;

knowledge base means carried on said data storage means for identifying a possible mode of failure;

input means in electrical communication with said digital data processing device;

output means in electrical communication with said digital data processing device;

visual display means for displaying macroscopic or microscopic views of selected part failures, said visual display means being in electrical communication with said digital data processing device;

expert system means controlling the digital data processing device for requesting and receiving, through the output device, information from a user while displaying at least one of said selected views on the visual display means, said view being associated with at least some of the requests for information;

program means for receiving responses from the user through the input device;

inference engine means for logically correlating said received information with said knowledge base to isolate possible failure modes; and

incident file means carried on said storage means for retaining a record of the information requested and received from the user.

2. A system according to claim 1 further comprising data base means controlling said digital data processing device for enabling a user to request data from or transfer data to the incident file means or the knowledge base means while displaying at least one of said macroscopic or microscopic views associated with the user'"'"'s request for data on the visual display means.

3. A system according to claim 2 further comprising information retrieval means for accessing data in the knowledge base means while displaying, on said visual display means, at least one of said macroscopic or microscopic views associated the knowledge base data.

4. A system according to claim 3 further comprising modifying means for periodically correlating data carried in said incident file means and modifying said knowledge base means in accordance with the correlated data.

5. A system according to claim 1 further comprising root failure analysis means controlling the digital data processing device for confirming the possible failure modes identified by the inference engines means by requesting additional information from the user while displaying, on the visual display means, at least one of said macroscopic or microscopic views associated with the request for additional information.

6. A system according to claim 5 further comprising data base means for controlling said digital processing device for enabling a user to request data from or transfer data to the incident file means or the knowledge base means while displaying, on the visual display means, at least one of said macroscopic or microscopic views associated with the user'"'"'s request for data.

7. A system according to claim 6 further comprising information retrieval means for accessing data in the knowledge base means while displaying, on the visual display means, at least one of said macroscopic or microscopic views associated with the knowledge base data.

8. A system according to claim 7 further comprising modifying means for periodically correlating data carried in said incident file means and modifying said knowledge base means in accordance with the correlated data.

9. A method for expert system part failure analysis, said method comprising the steps of

requesting failure related information from a user through a digital data processing device;
