This thesis describes the development of a QFD information model established in
an environment where design information is shared between software applications. The
main objectives of the research are to establish a QFD information structure within a
Product Data Model and to demonstrate how this enables an intelligent, knowledgebased
analysis of QFD information contained in a Product Model.
The generic structure of the QFD information has been defined and implemented
in prototype software and its value is demonstrated through experimentation in two
case studies. Successful implementation of the case studies proved that the QFD
information structure is able to capture QFD information as persistent objects residing
in a Product Model. It also demonstrates that an intelligent knowledge-based QFD
expert can be implemented alongside the QFD information model to accomplish useful,
consistent, reasoned analysis of QFD information.
The research has achieved its aim to provide a new contribution in the product
design domain, and to the effectiveness of Concurrent Engineering activities, through
better use of Quality Function Deployment.
