A quality function deployment model by social network and group decision making: Application to product design of e-commerce platforms

Quality function deployment (QFD) is an effective method to convert customer requirements (CRs) into design requirements (DRs) by constructing house of quality (HOQ). With the rapid growth of the e-commerce market, it is a new challenge to utilize the available online reviews to facilitate the implementation of QFD. Therefore, this paper proposes a novel QFD model from the perspective of group decision making (GDM) and social network analysis (SNA), then applies the proposed model to product design under Chinese e-commerce scene. Firstly, this paper extracts CRs from online reviews on e-commerce platforms, and the initial HOQs can be constructed. Then a bilateral negotiation GDM method based on SNA is carried out to generate a consensus-based HOQ, and therefore the final priorities of DRs can be obtained. Finally, a case study is provided to illustrate the applicability, and some discussions and comparative analysis are also conducted. The result indicates that the proposed method can generate effective and stable results for QFD implementation in real-world e-commerce scenario.

Coping with diversity ratings in prioritizing design requirements in quality function deployment: A consensus-based approach with minimum-maximum adjustments

Quality function deployment (QFD) is a powerful customer-driven quality management tool that improves product quality by translating customer requirements (CRs) into design requirements (DRs) of a product. It is essential in QFD to obtain the importance ratings of DRs from the importance ratings of CRs and the relationship between CRs and DRs. However, two basic challenges hinder the effective implementation of QFD: (i) vague assessments of the relationship between CRs and DRs due to the inherent uncertainty in human judgement; and (ii) diverse importance ratings of DRs owing to the heterogeneity of the QFD team members. To this end, this study provides a consensus-based QFD to derive the consensual importance ratings of DRs, where linguistic distributions are used by the QFD team to express their assessments of the relationship between CRs and DRs. In the consensus-based QFD, a minimum–maximum adjustment consensus model is presented to assist the QFD team in deriving a consensual assessment regarding the relationship between CRs and DRs. This model is designed by minimizing the maximum adjustment between the original and the adjusted linguistic distribution assessments. Moreover, some desirable properties of the minimum–maximum adjustment consensus model are investigated. Finally, a case study, a detailed sensitivity analysis, and a comparison analysis are presented to illustrate the validity of our proposal.

Understanding mission objectives and priorities with QFD

AbstractTranslating the customer's perception of quality and performance into technical terms and requirements for a product is important for guiding design, verification, and process development. Capturing the unspoken priorities and communicating them through the organization can efficiently guide the product or service development towards solutions that meet the customers’ needs. The methods used at Kongsberg Defence Systems today do not sufficiently capture and communicate the voice of the customer and their fundamental needs. The research uncovered that key decision makers in the organization had significant variance in their understanding of customer priorities, and a partial misalignment with the priorities provided by customer representatives. The implementation of Quality Function Deployment (QFD) for the Joint Strike Missile provided an effective communication tool for customer needs, and illuminated the relative importance of system attributes and how they relate to the customer's priorities. This paper argues that the Quality Function Deployment is a valuable tool communicating mission objectives, to enable innovation, and to guide verification and validation efforts at a later stage. For complex products, however, QFD shows weaknesses that must be addressed to support efficient decision making.

The quality function deployment method under uncertain environment using evidential reasoning: a case study of compressor manufacturing

In recent years, the issue of customer satisfaction achieving on the basis of improving service quality has been widely investigated. To achieve this goal, one of well-structured method is quality function deployment (QFD). QFD is an approach defining customer requirements (CRs) and translating them into relevant design requirements (DRs). The successful implementation of QFD requires a significant number of subjective evaluations of both customers and QFD team members. The QFD team members evaluate relationships between DRs and CRs and interrelationships between DRs. The customers evaluate relative importance of each CRs. In the basic QFD, crisp values are used for determining relationships between DRs and CRs, but the mentioned method are not suitable to address the subject of uncertainty, since in most cases QFD team express their opinions with uncertainty and therefore resulting in inappropriate implementation of QFD. This paper aims to apply a QFD method based on evidential reasoning approach to handle uncertain evaluation information provided by QFD team in compressor manufacturing. This method is able to consider uncertainties such as interval, imprecise and incomplete data in utilizing belief structure and then aggregating them to prioritize engineering DRs according to CRs.

Hybrid customer requirements rating method for customer-oriented product design using QFD

Quality function deployment (QFD) is a well-known customer-oriented product design methodology. Rating the final importance of customer requirements (CRs) is really a very essential starting point in the implementation of QFD, since it largely affects the target setting value of design requirements. This paper aims to propose a novel method to deal with the relative importance ratings (RIRs) of CRs problem considering customers' diversified requirements and unknown information on customers' weights, which is an indispensable process for determining the final importance ratings of CRs. First, a new concept of customer's assessment structure is proposed according to the basic idea of grey relational analysis (GRA), and then a constrained nonlinear optimization model is constructed to describe the assessment information aggregation factors of CRs considering customers' personalized and diversified requirements. Furthermore, an immune particle swarm optimization (IPSO) algorithm is designed to solve the model, and the weight vector of customers is obtained. Finally, a car door design example is introduced to illustrate the novel hybrid GRA-IPSO method's potential application in determining the RIRs of CRs.
