Abstract: Quality function deployment (QFD) is becoming a widely used
customer-oriented approach and tool in product design. The inherent
fuzziness in QFD modeling makes fuzzy regression more appealing than
classical statistical tools. A mathematic method to determine the
relation functions between customer requirements and engineering
characteristics and correlation functions among engineering
characteristics using optimization theory combined with fuzzy regression
theory is presented, and furthermore a modeling approach for QFD
planning is proposed. The proposed modeling approach would be applicable
to a wide spectrum of design problems where multiple design criteria and
functional design relationships are interacting and/or conflicting in an
uncertain and fuzzy product design process. The proposed approach would
allow a design team to reconcile tradeoffs among the various customer
satisfaction levels as well as the inherent fuzziness in the system.
