Study and Application on the Integration of Quality Tools Based on QFD

To eliminate the effects caused by conflict,fuzziness and potential failure in the course of design and manufacturing of the product,the study of integration between TRIZ,FMEA,DOE,SPC and QFD is conducted.Through analyzing the relationships between various quality tools and QFD,a integrated system model based Quality Function Deployment(QFD) is presented to support the development of product,specific methods and tools are provided to solve the problem of each phase,and the integrated QFD system(IQFDS) is developed.A application case of designing the reel of the crane illustrates that QFDS can not only overcome the drawbacks in traditional QFD,but also optimize the process of design and manufacturing,improve and enhance the level of quality,and furthermore satisfy the needs of customers.
