MethodDevelopment and comparative analysis of an intelligent system with various data structures and matching algorithms.

ProcedureAn Intelligent Failure Analysis System (aIFAS) was developed using a knowledge base derived from commercial laboratory reports. The system was enhanced with a parametric analytic engine to compare five candidate metrics for case matching against a set of failure cases. A more compact file structure for attribute representation was explored, and new metrics (Relative Time Unit and Performance Score) were introduced.
