Abstract

An integrated multivisual expert system maintenance advisor system includes an expert system module, a photo-library module and a hypermanual module. The photo-library module and the hypermanual module are linked to each other and to the expert system module. The expert system module utilizes backward and forward chaining "if-then" program rule logic. The rule logic allows for computer program inference reasoning using maintenance technician entered failure systems. The photo-library module includes digitized photograph display processor programming in which magnetically stored digitized photographs are retrieved and processed. The hypermanual module allows instantaneous search and retrieveal of visual display screen of ASCII text character strings by either direct topic search keys or by related or indirect topic search keys, and provides repair and replacement information to the maintenance technician.

Claims

1. An integrated multivisual expert system maintenance advisor system, which comprises:

an expert system module;

a photo-library module operatively linked to the expert system module;

a hypermanual module operatively linked to the photo-library module and the expert system module;

a computer having a computer memory, the expert system module, photo-library module and hypermanual module forming at least portions of the computer memory;

a keyboard operatively linked to the computer;

a visual display screen operatively linked to the computer; and

a printer operatively linked to the computer, the computer memory portion of which the hypermanual module is formed having stored therein repair and replacement information.

2. An integrated multivisual expert system maintenance advisor system as defined by claim 1, wherein the expert system module utilizes backward and forward chaining "if-then" program rule logic.

3. An integrated multivisual expert system maintenance advisor system as defined by claim 1, wherein the expert system includes a maintenance technician interface portion, an inference engine portion operatively linked to the maintenance technician interface portion, a rule base portion operatively linked to the inference engine portion, and an information base portion operatively linked to the rule base portion.

4. An integrated multivisual expert system maintenance advisor system as defined by claim 1, wherein the computer memory portion of which the photo-library module is formed has stored therein digitized photographs.
