Abstract or Description

Defect prediction, using the knowledge based system approach, is being developed for the case of longitudinal surface cracks. Knowledge about longitudinal cracking is in the form of databases, mathematical models and qualitative information. Much of this comes from the technical literature on related topics, but is supplemented by plant experience, as well. Knowledge based systems provide the facility for handling such types of knowledge, with control particulars left up to the system builder The current implementation is forward chaining and uses the OPS5 inference engine. The system involves the use of all three types of knowledge, but more mathematical models are being sought.
