Quality function deployment (QFD) is a product development process used to achieve higher customer satisfaction: the engineering characteristics affecting the product performance are designed to match the customer requirements. From the viewpoint of QFDs designers, product design processes are performed in uncertain environments, and usually more than one goal must be taken into account. Theref...

This paper conducts a comparison analysis of some of the most common defuzzification techniques which helps rank fuzzy weights calculated from fuzzy comparison matrices through Fuzzy Analytic Hierarchy Process. Ranking of weights calculated through FAHP algorithms is of critical importance as it directly effects the decision making process. More so ranking of fuzzy numbers is also important in ...

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 ...

Various extensions of the environmentally-conscious quality function deployment (QFD) were explored to address sustainable product design. To provide a systematic computational platform, integration fuzzy set theory and multiple criteria decision making (MCDM) methods becomes popular approach. However, most applications QFD-MCDM approaches are concentrated on planning phase, which limits overal...

Abstract—Considering its need to trade-off multiple criteria exhibiting vagueness and imprecision, supplier selection is an important multi-criteria decision making problem. Vague and imprecise judgments inherent in numerous features of supplier selection call for using linguistic assessments rather than exact numerical values. In this paper, a novel fuzzy multi-criteria group decision making a...

Fuzzy quality function deployment (QFD) has been extensively used for translating customer requirements (CRs) into product design requirements (DRs) in fuzzy environments. Existing approaches, however, for rating technical importance of DRs in fuzzy environments are found problematic, either incorrect or inappropriate. This paper investigates how the technical importance of DRs can be correctly...

Recently, special attention has been paid to artificial groundwater recharge in water resource management in arid and semi-arid regions. Water resources distribution in these regions is extremely uneven, both in spatial and temporal forms and groundwater is the only water resource and is a major constraint on economic and social development. Artificial groundwater recharge is considered an appr...

higher education plays a very vital role in developing human resources as well as economic ones in every country. in so doing, the act of evaluation would help the decision makers as well as managers to spot the weaknesses to use the required provisions to work more effectively. the present study with a different approach toward the designing a comprehensive evaluation expert system using fuzzy...

Quality function deployment (QFD) has been widely used in many fields; it is one of the structured approaches that are used to translate customer needs into specific quality development. However, in the traditional QFD approach, each element’s interdependence and customer requirements (CRs) for green supply are not usually treated systematically. The important function of green product lifecycl...
