|
Although case based design(CBD) had been considered an appealing supporting technology for intelligent design,its development was not satisfying.One of the main hinders is the lack of deep research on learning.The way of storing and indexing cases plays a key role on the learning function of a CBD system.A feature-based learning approach for CBD system was presented in this paper.The method firstly created mappings from stamping features and corresponding die designs.Secondly,fuzzy clustering was applied to put similar cases into one cluster.Finally,redundant attributes were removed and production rules were extracted from the clustered decision table by applying Rough Set Theory.Running of a prototype system based on this method shows that it is feasible and suitable for learning knowledge from die designs.
