GCDK: Generation and Conservation of Design Knowledge
Project GCDK is a collaboration between the AI Branch at NASA Ames Research Center and the
Center for Design
This project is researching tools and methodologies for modeling,
indexing and retrieval of design information during a design process.
These tools and methods will be integrated with the
Engineering Design Notebook being developed in the SHARE
project at the Center for Design Research.

The core objective of this projects are:
of knowledge generated during a design process. Our hypothesis is
that, design knowledge conservation (capture, representation,
reasoning and retrieval) will be far less costly than re-inventing
These objectives are being achieved by developing tools and
methodologies which can be integrated within the computational and
social working environment of industrial designers. Particular
attention is paid to have this integration in a manner so that the
capture, indexing and modeling happens during the design process
rather than after it.
Research in this project has three parallel efforts,
These parallel efforts ensures our results and keeps the
research grounded in reality through constant feedback from designers.
- Design Methodology Research,
- Computational Tool Development and
- Real Design
The activity of design methodology research is aimed at better
understanding the design process and the information needs of
designers. It results in frameworks and methods which can guide the
development of computational tools. There tools are then made
available to designers and the usage of the tools is closely studied
and analyzed. The results from these user studies are used to inform
the further development and refinement of the tools. The publications
below cover in detail the results from our research over the past
