Product variant generation is fundamentally different in Electrical
Computer-Aided Design (ECAD) rather than Mechanical Computer-Aided
Design (MCAD). The difference lies in the logical relationships between
ECAD components. It is not straightforward to select a previous product design
to aid product variant generation. Therefore, a new methodology suitable for
web-based delivery to support ECAD product variant design is described. Part
of the methodology proposed is based on fuzzy logic to select previous ECAD
designs from a database of case bases. An additional cost engineering module
is proposed to provide the functionality of cost optimisation of the subset of the
designs fulfilling a predefined criteria list. The other parts of the methodology
have been fully implemented to allow automatic generation of designs
in software.
