Objectives:

  • Integrated engineering knowledge-bases and engineering digital libraries
  • Intelligent dicision support tools for design
  • Techniques to leverage legacy knowledge

Accomplishments

  • Message model for distributed design
  • Process archival methodologies to populate design knowledge-bases
  • Retrieval strategies for design knowledge-bases
  • Graph-based structres for knowledge modeling
  • Geometric search algorithms
  • Collaborative/Conceptual interfaces
  • Internet-Based Design Repository
  • Deploying Repository site
  • Initial implementation of Conceptual Query Interface, Structure Matcher
  • Data acquisition--CAD data, Process/Assembly Plans
  • Integrated with fabrication services
  • Integrate Repository with K-base system
  • Approximation algorithms for Structure Matching, Distance Measurement
  • Enhanced design graph representation
  • Experimentation and testing of conceptural design/query interface

Impact

  • Enables variational design
  • Access and reuse of legacy data and information
  • Platform for networked collaboration on and knowledge sharing about design problems
