Application of expert system for quality and process design of steel plates

In order to automate the quality and process design of steel plates, an expert system based on the case-based reasoning system has been developed. The case-based reasoning is a plausible approach for design problems, as knowledge in such problems is almost always fragmentary. However, it is also true that raw cases contain mistakes. In this system, model cases are extracted from raw cases, generalized somewhat, and then referred to as good designs. Using model cases is also effective to shorten inference time. This system shortened design work time by one-eighth and contributed to the standardization and inheritance of skilled design techniques.<>
