- Abstract
Quality Function Deployment (QFD) is widely used in optimizing schemes (e.g., product designs and materials evaluation). However, the traditional QFD focuses only on the demands of quality and measures to assure the quality. Furthermore, the general methods to evaluate the weight of factors used in QFD include much of subjective aspect, which could introduce bias to the outcomes. This paper proposes an innovative systematic approach for optimal selection, which could be incorporated with global trends in manufacturing (e.g., remanufacturing, green manufacturing), materials research (e.g., eco-friendly plastics), and beyond. First, the traditional QFD is extended to cover the whole lifecycle of products and materials so that the optimization would be comprehensive and consistent with the latest requirements, such as sustainability. Second, the weight of each factor in the improved QFD is derived according to a method based on the combination of analytic hierarchy process (AHP) and entropy theory, which integrates the merit of both subjective and objective methods. Third, an evaluating method originating from grey relational projection is employed to select the best solution from the potential schemes. As an example, the designs of refrigerators are evaluated using the proposed approach. The results suggest that this approach is capable to solve complicated multi-criteria decision-making problem, and be beneficial for much research, including but not limited to product design
