摘要: 针对产品概念设计阶段中可持续设计需求重要性难以准确评估的问题,提出一种考虑用户权重不一致性和需求交互影响的可持续设计需求评估模型,以支持产品开发在下游过程中的环境影响评估。提出基于可信度函数的改进Kano模型获取用户可信度实现可持续设计需求的评价数据集成,并利用信息熵得到可持续设计需求的初始权重。在此基础上,借助模糊决策和试验评估实验室法(Decision-making and trial evaluation laboratory,DEMATEL)获取各个需求的影响关系有向图,构建考虑需求交互影响的综合权重函数,实现可持续设计需求的排序和重要性分析。以电冰箱产品开发为例实现了13个可持续设计需求重要性的评估和分析,同时进行方法对比和敏感性分析,验证所提方法的可靠性和可行性。

Abstract: To address the problem that the importance of sustainable design requirements in the product conceptual design phase is difficult to assess accurately, a sustainable design demands evaluation model considering the inconsistency of user weight and demand interactive is proposed to support the environmental impact assessment of product development in the downstream process. An improved Kano model based on the trust function is proposed to obtain the users’ trust to integrate the evaluation data of sustainable design demand, and the initial weight of each sustainable design demand is obtained by using information entropy. On this basis, the fuzzy Decision-making and trial evaluation laboratory (DEMATEL) is used to construct a directed graph of the impact relationship of demands, a comprehensive weight function considering the demands interactive impact is formed to realize the ranking and importance analysis of sustainable design demands. Finally, a refrigerator is used as a case study to realize the evaluation and analysis of 13 sustainable design demands’ importance, and the results comparison and sensitivity analysis are carried out to verify the reliability of the proposed approach.

Key words: improved Kano model, fuzzy DEMATEL model, sustainability, trust model, conceptual design
