Abstract

THIS PHASE II EFFORT BUILDS ON THE PHASE I WHICH ESTABLISHED THE FEASIBILITY OF COMBINING A MODERN PORTABLE COMPUTER WITH AN EXPERT SYSTEM SHELL OPERATED BY VOICE, AND AUGMENTED BY GRAPHICS, TO AID A MAINTENANCE TECHNICIAN IN THE DIAGNOSIS AND REPAIR OF COMPLEX NAVY EQUIPMENT. EXPERT SYSTEMS RULES, REPRESENTATIVE GRAPHICS, AND SPEECH VOCABULARY WERE DEVELOPED WHICH LEAD THE TECHNICIAN THROUGH THE DIAGNOSIS AND REPAIR PROCEDURES OF TWO AN/BBQ-5 SONAR SYSTEM PROBLEMS WITHOUT REFERENCE TO PRINTED DOCUMENTS. A REPORT CAPABILITY IS PROVIDED WHICH COLLECTS INFORMATION DURING THE DIAGNOSES AND REPAIR PROCESS AND PRINTS OUT A REPORT. THE PHASE II WORK IS TO DEVELOP A HORIZONTALLY INTEGRATED SOFTWARE AND HARDWARE SYSTEM THAT SERVES THE NEEDS OF THE REPAIR TECHNICIAN. IT INCLUDES ANALYSIS OF THE METHODS OF ENTERING THE DIAGNOSTIC KNOWLEDGE TREE, DISPLAY GRAPHIC REQUIREMENTS, REPORT GENERATION FOR OPERATOR AND MANAGEMENT NEEDS. THE SYSTEM INTEGRATED FOR USE WITH THE AN/BQQ-5 WILL BE FURTHER EXPLORED TO DEVELOP A MODULAR INPUT SYSTEM, ZOOM AND HIGH RESOLUTION GRAPHICS, ALTERNATIVE INPUT SYSTEMS, SUCH AS ADVANCED SPEECH RECOGNITION AND SYNTHESIS, AND TOUCH PADS. THE INITIAL TOOL FOR THIS RESEARCH WILL BE THE DOLCH COMPUTER AND THE XI PLUS EXPERT SYSTEM.
