Creation, Validation, Testing, and Data Management of a Knowledge Base Designed for a Technician's Assister System for the AN/SQS-53B, Unit 26, Using a Fault Isolation System Shell
Abstract
A system using the Fault Isolation System (FIS) shell was designed for Unit 26 of the SQS-53B Sonar System. the sonar system unit has a mixture of analog and digital components. Over 100 replaceable modules are in Unit 26. The knowledge base created to describe the circuit topology of Unit 26 contains over 3,000 rules and was ten times larger than any other system modeled for FIS. A methodology is described for creation of large knowledge bases and of the data management requirements. A format of the data management structure is presented in this report. Software written in C for data manipulation is described in this report. The diagnostic, compilation, verification, and validation process for the creation of a viable FIS knowledge base is also presented in this report. Knowledge base manipulation software was written in LISP or in C interfaced to LISP on a SUN 3/110. Validation was performed at the Naval Underwater Systems Center, New London, CT.
