Quality function deployment (QFD) is a method used for the manufacturing process of a product or service that is devoted to transforming customer requirements (CRs) into appropriate engineering characteristics (ECs) by specifying the importance of the ECs and then setting their target values. Confronting the inherent vagueness or impreciseness in the QFD process, we embed the fuzzy set theory i...

The purpose of this paper is to improve service quality of freight forwarders and explore the quality function deployment (QFD) in terms of quality management technique. Freight forwarder business is mainly characterized by lower capital investment and entry barrier comparing with a shipping line. Freight forwarders usually work closely with shipping or airline companies as intermediary agent a...

Catering service of high speed railway (CSHR) is an important part of railway passenger service. This paper suggests a new use of Fuzzy Quality Function Deployment (F-QFD) for distribution center locations evaluation in CSHR (DCLP-CSHR) as a preliminary step for distribution network design. Fuzzy sets concept is incorporated to deal with imprecise nature of the linguistic judgments of decision ...

In Quality function deployment (QFD) approach, customers tend to express their needs in linguistic terms rather than exact numerical values and these generally contain vague imprecise information. To overcome this challenge use the method more effectively for complex customer-oriented design problems, paper introduces a novel intuitionistic Z-fuzzy QFD based on Chebyshev’s inequality (CI) appli...

the quality function deployment (qfd) is a very helpful method to analyze the customer's desires with solutions of problems along a new design to generate high quality and competitive developed products to generate high quality and competitive ergonomic products and processes. this method employs a wide range of applications for translating customers’ needs into technical requirements to f...

This paper applies the quality function deployment (QFD) theory to improve teaching of entrepreneurship education, and puts forward QFD model education improvement. First all, constructs a series houses by mining customers’ demand for including house design, implementation control. The customer demands are expanded specific steps process, establishment target in local universities through reali...

The interdisciplinary complexity of modern construction projects has made meeting customer needs and requirements a difficult task. Under the current model, decisions affecting the early stages of design when designers have the largest impact on the final cost and functionality of a given product are approached in an informal and non-homogeneous manner. This study proposes an alternative approa...

As the quality of product/service requirements of people dining rising. Because of the economic recession, the food and beverage industry is facing a strong competition. Only by understanding the true needs of consumers can their requirements are satisfied. For this reason, this study to use Quality Function Deployment (QFD) understanding the true needs of consumers, and explore a the best opti...

Changes of software requirements are inevitable during the development life cycle. Rather than avoiding the circumstance, it is easier to just accept it and find a way to anticipate those changes. This paper proposes a method to analyze the volatility of requirement by using the Quality Function Deployment (QFD) method and the introduced degree of volatility. Customer requirements are deployed ...
