Line 15:
development of the basic foundations of the next generation of
CAD systems suggested a core representation for design
information called the '''NIST core product model''' (CPM) <ref>4</ref> and
a set of derived models defined as extensions of the CPM (e.g.
<ref>5</ref><ref>15</ref>). The NIST core product model has been developed to

good instance of this approach. The other is to represent a
collection of design knowledge into a certain case for
description. '''Case-based design''' is an example of this approach

design knowledge representation. For instance, researchers at

capture the dynamic design knowledge in a certain format for
design re-use and archive. A few research efforts have been

process rather than the product. It uses design matrix to
represent the design process as a structured set of issues and
activities. Together with the common '''product data model'''
(CPDM), PROSUS supports the capture of all outputs of the
design activity.
'''Ontologies''' are being used for product representation (e.g. <ref>10</ref>).
Research suggests, therefore, that there is a need to provide
'''computer support''' that will supply clear and complete design
knowledge and also facilitate designer intervention and
customization during the decision-making activities in the
design process <ref>11</ref>. For example, WebCADET <ref>12</ref> is a design
support system that uses distributed Web-based AI
tools. It uses the ‘‘AI as text’’ approach, where '''knowledge-based systems''' (KBSs) can be seen as a medium to
facilitate the communication of design knowledge between
designers. The system can provide support for designers when
