Conclusions  CBR puts forward a paradigmatic way to attack AI issues (problem solving, learning, general/specific knowledge, different reasoning methods--rules/case-based)  CBR puts problem solving and learning as two sides of the same coin ( problem solving uses the results of past learning episodes while problem solving provides the backbone of the experience from which learning advances)

Contributions b Built a system using CBR techniques to solve engineering design problem, currently, the system can be used in Rolling Bearing design problem. b The built system can be used as prototype of CBR system, which can be expanded to other domain through adding domain knowledge b Built a Graphical User Interface for reasoning system

Future Work b Knowledge Acquisition issue: Develop good methodologies to automatically /dynamically perform knowledge acquisitionDevelop good methodologies to automatically /dynamically perform knowledge acquisition b Index Scheme issue: Develop good methodologies to dynamically specify index features/specify index featuresDevelop good methodologies to dynamically specify index features/specify index features b Cross-Domain issue: Develop good methodologies to expand current system to solve cross-domain problems.Develop good methodologies to expand current system to solve cross-domain problems. b Knowledge engineering issue: Good methodologies to perform case collection / maintain case-baseGood methodologies to perform case collection / maintain case-base b Graphical reasoning issue: Integrate CAD/IDEAS into our systemIntegrate CAD/IDEAS into our system
