Six Sigma and Design for Six Sigma (DFSS) offer a new approach to Total Quality Management with a more integrated approach, standardized training and certification, and financial accountability for i nvestment in improvements. A core principle of DFSS is the Transfer Function (y=f(x)), whereby customer requirements are transferred into Critical-to-Quality requirements (CTQ). DFSS uses the House...

Quality function deployment (QFD) is a customer-driven approach, widely used to develop or process new product to maximize customer satisfaction. Last researches used linear physical programming (LPP) procedure to optimize QFD; however, QFD issue involved uncertainties, or fuzziness, which requires taking them into account for more realistic study. In this paper, a set of fuzzy data is used to ...

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...

This article presents an integrated approach to optimize cost while respecting the customer perception of a product using a modified Quality Function Deployment (QFD) method. This QFD method helps a design team to determine the effect of various design strategies for customer satisfaction. The new QFD method uses a two-phased approach for finding an optimum design strategy. During the first pha...

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 ...

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...
