Prioritizing technical requirements in QFD by integrating the grey relational analysis method and analytic network process approach

No matter at what stage in product design or product quality improvement, the technical requirements (PTRs), or engineering characteristics impacting on product performance are mainly identified and improved to optimize customer needs (CNs) as greatly as possible. Quality function deployment is utilized as a powerful tool for improving product design level and enhancing product design quality. In this study, an integrated framework based on grey relational analysis (GRA) method and analytic network process (ANP) approach is proposed to determine the importance degrees of PTRs in designing a product. An application in a Turkish Company producing PVC window and door systems mentioned in a previous study is presented to illustrate the proposed framework.
