Abstract

SCT has developed an expert maintenance tool (XMAN II) to assist the technician in evaluating engine monitoring system (EMS) data. The design and function of the XMAN II system are described, and a sample troubleshooting session to demonstrate the diagnostic and user interface features resident in the XMAN II program are discussed. XMAN II implements a comprehensive information analysis technology using a knowledge-based algorithmic approach. Information analysis in this context means the application of structured and unstructured methods to data recorded from remote sensors and manual tests for the purpose of deducing facts about the physical system, including actual condition, imbedded faults, and health prognosis. The information resides in databases. Methods are stored in knowledge bases. XMAN II implements a seamless integration of data, knowledge, and control
