“…It is a method that collects vaguely expressed quality requirements from the market and uses them to actual product design works [18]. Example use of QFD in product design and development process can be seen in many research works like for standing aircraft passenger seat [19], school furniture [20] and also for personal computer [21]. In this study, QFD method is applied for the development of improved in-flight food delivery and waste collection system for application onboard commercial transport aircraft.…”

The objective of this paper is to identify the driving needs for an improved food delivery and waste collection system to be implemented onboard of the commercial passenger transport aircraft. Quality Function Deployment (QFD) method has been applied to establish the design requirements from the point of view of the passengers and airlines. The collected data from conducted public survey and also interview sessions with the experts from the airlines are utilized to construct the House of Quality (HOQ). In short, it has been found that safety and cleanliness are the two top prioritized design requirements for a new food delivery and waste collection system. On the other hand, the type of carriage, overall profile of the system and also the operating mechanism used for the system are top technical design parameters that can influence the successful achievement of the design requirements. Findings from this study will be further utilized to generate design options for the improved food delivery and waste collection system.

“…There are numerous publications on QFD in the literature (Kim, 1997, Mrad, 1997, Persson et al, 2000, Gerling et al, 2002, Han et al, 2004, Yoram and Eyal, 2005, Chan and Wu, 2005, Bhattacharya et al, 2005, Dweiri and Kablan, 2005, Poel, 2007, Lai et al, 2007. Various applications within the literature can be grouped into three categories: QFD implementations before the design stage, QFD implementations during the design stage, and QFD implementations after the design stage (Dikmen et al, 2005).…”

“…Mathematical programming is one of these optimization methods. The linear programming model is used to maximize the overall customer satisfaction (e.g., Chen and Ko 2009;Lai et al 2007). Park and Kim (1998) used integer programming to optimize product design in the QFD.…”

Quality function deployment (QFD) is a customer-driven approach, widely used to develop or process new product in order 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 address linguistic values parameterized by triangular fuzzy numbers. The proposed integrated approach includes analytic hierarchy process (AHP), QFD, and LPP to maximize overall customer satisfaction under uncertain conditions and apply them in the supplier development problem. The fuzzy AHP (FAHP) approach is adopted as a powerful method to obtain the relationship between the customer requirements (CRs) and engineering characteristics (ECs) to construct the house of quality (HOQ) in QFD method. LPP is used to obtain the optimal achievement level of the ECs and subsequently the customer satisfaction level under different degrees of uncertainty. The effectiveness of proposed method will be illustrated by an example.
