摘要
A quantitative measure-based method for the design and evaluation of sustainable products is proposed. The method uses multi-criteria in product design to meet sustainable requirements from qualitative criteria to quantitative metrics. The method integrates quality function deployment concepts with the life cycle assessment to establish a quantitative method for sustainable product development. It considers both customer needs and sustainable requirements by mapping these needs into design details using the axiomatic design and benchmarking methods. The method is applied in the wheelchair design. Four popular wheelchairs in the market are selected as benchmarks and are rated based on customer needs and sustainable criteria. The design matrix identifies the relationship of functional requirements and design parameters of the wheelchair. Compared to the best benchmark product, the proposed wheelchair can reduce costs by 13.8%, environment footprints 18.55%, mass 4.5%, and components 2.2%.
提出了基于量化的可持续产品设计和评估方法.该方法使用产品设计的多标准来满足可持续产品从定性到定量的设计要求.建立的可持续发展产品定量方法集成了质量功能展开的概念与生命周期评估方法.它同时考虑客户需求和可持续发展的要求,并通过公理设计映射和基准测试方法将这些需求变为设计细节.将提出的方法应用在轮椅设计中.其设计基准选用了4种常用的轮椅并将其根据客户需求和可持续要求评级.设计矩阵用来确定轮椅功能要求和设计参数的关系.与最好的基准产品相比,所设计的轮椅可以降低成本13.8%,环境足迹18.55%,质量4.5%,以及组件数量2.2%.
