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.
