Use of Hypermedia as a User Interface for an Artificial Intelligence-Based Problem Solver.

摘要

This thesis discusses the use of a hypermedia system as the user interface for an expert system. The hypermedia system allowed dynamic creation and editing of the user interface, and collected and transmitted information from the user to the expert system. The expert system, which remains transparent to the user, uses this information to recommend a solution to the problem or to determine more information is needed from the user. Regardless, the expert system communicates these results to the hypermedia system, which then displays them to the user. Specifically, the prototype developed as a part of this research was designed to help Aerospace Guidance and Metrology Center (AGMC) depot-level technicians troubleshoot the Dual Miniature Inertial Navigation Systems (DMINS) Inertial Measurement Unit (IMU), which is being used on fast attack submarines. Currently, DMINS technicians information from automatic test equipment (ATE) to guide their troubleshooting actions. This ATE is driven entirely by test failures resulting from the tested IMU signals being out of the specification limits. In addition to using these signals, the prototype uses IMU signals, not being validated by the current test, to detect problems before a test failure occurs. The capability to find problems prior to a test failing, can significantly decrease the time needed to test an IMU. Theses. (jhd)
