The Application of Case‐Based Reasoning to Ultrasonic Data for Use in Inspection Qualification

This paper describes the application of case‐based reasoning (CBR) to provide decision support for the NDT engineer during Inspection Qualification. A key element of this process is to present experimental evidence on the effectiveness of the inspection. A prototype for the system has been developed using a case‐base which describes the defect, the probe and response. This paper discusses the motivation for the system, the case structure, weightings, similarity measures, retrieval techniques and its design and implementation.
