The critical product planning phase, early in the product development cycle, requires a design tool to set engineering priorities, capable of selecting the preferred design concept and setting target levels of engineering performance to guide the later product development stages, while considering the needs of both the consumer and producer. The Quality Function Deployment (QFD) method was deve...

Quality function deployment (QFD) can provide a means of translating customer requirements (CRs) into engineering characteristics (ECs) for each stage of product development and production. The main objective of QFD-based product planning is to determine the target levels of ECs for a new product or service. QFD is a breakthrough tool which can effectively reduce the gap between CRs and a new p...

In this study, Turkish automotive sector needs for flexibility will be determined, and the relationships between flexibility levers and flexibility performance criteria will be evaluated with respect to the sectoral needs. The choice of the appropriate lever combinations will be made for the sector by using the results of this evaluation. The flexibility strategies will be ranked by using a fuz...

Little academic work exists on managing reference model development and measuring reference model quality, yet there is a clear need for higher quality reference models. We address this gap by developing a quality management and measurement instrument. The foundation for the instrument is the well-known Quality Function Deployment (QFD) approach. The QFD-based approach incorporates prior resear...

This chapter demonstrates how a neuro-fuzzy approach could produce outputs of a further-modified multi-criteria decision-making (MCDM) quality function deployment (QFD) model within the required error rate. The improved fuzzified MCDM model uses the modified S-curve membership function (MF) as stated in an earlier chapter. The smooth and flexible logistic membership function (MF) finds out fuzz...
