ABSTRACT
The change of mechanical design requirements is throughout the whole life cycle, if not handled timely and effective, will affect the component quality and mechanical product development speed. Firstly, the traditional quality function deployment is extended to Dynamic Quality Function Deployment (DQFD) in order to adapt to the changing requirements, meanwhile the author builds three-dimensional house of quality as its core tool. According to the vagueness and uncertainty of customer requirements, the author provides the systematic analytical framework of mechanical design requirements based on DQFD combining with grey system theory especially GM (1, N) and calculate the importance of requirements and the relationship between requirement and technology by means of grey relational algorithm and then converted to sequence of technical characteristics importance. Through the application in the design and development of mechanical product in the future, it will be proved to reduce the cost of information collection and improve the accuracy of information processing and improve the quality and credibility of mechanical product and component.
