主　　题：quality function deployment(QFD) database class encapsulation fuzzy inference 

摘      要：Complicated product QFD system design information including design and manufacturing, operation and maintenance as well as relative supply information, all are tightly related to the product life cycle cooperative design and the process of establishing the QFD system. In the early stage of product design, we can only get the fuzzy and unreliable information. With design going, the fuzzy and unreliable information become less and less. The defect of the traditional QFD is not deal with the fuzzy contents very well. Adopt database class encapsulation and fuzzy inference technology, and then discuss the realization of QFD system based on VFP database. The structure of the fuzzy QFD system based on database class s encapsulation is built and the work flow of fuzzy algorithm based on VFP software is presented. In the analysis of fuzzy QFD process, fuzzy inference is adopted. A developed prototype system and an example have verified some presented techniques and the research results are the basis of the future development.
