【Abstract】 A mathematic approach was presented to determine the relation functions between customer requirements and engineering characteristics and correlation functions among engineering characteristics. The presented approach utilizes fuzzy regression analysis theory combined with fuzzy optimization theory with asymmetric triangular fuzzy number coefficients. A multigoal programming model for QFD was developed to maximize the customer satisfaction with limited recourses. The proposed model is applicable to various design problems, which multiple design criteria and functional design relationships are interacting and/or conflicting in an uncertain and fuzzy product design process. And it can help a design team to identify relative and correlative functions, reconcile tradeoffs among the various customer satisfaction levels and optimize engineering characteristic target values.更多还原
