目的 从可持续设计角度出发，为了更好地平衡用户、企业、环境、资源等多方需求的综合满意度，对户外分类垃圾桶可持续设计评价方法展开研究。方法 通过实地观察和访谈调研收集了多方需求，并利用双因子五阶Likert量问卷采集了初步需求的满意度调查数据;采用Kano模型分析计算需求敏感度并完成需求的筛选;将筛选后的需求和相应的敏感度分别作为评价指标和指标权重，完成了可持续设计评价指标体系的构建;结合灰色关联评价算法，对户外分类垃圾桶设计方案进行了评价实践和验证。结果 以12款户外垃圾桶设计方案作为评价实例，不仅实现了方案的综合得分排序，还通过单指标优势对综合最优方案做了进一步的优化。结论 实践结果表明，基于多方满意度户外分类垃圾桶可持续设计评价方法，能够有效评判户外分类垃圾桶的可持续设计质量，并帮助设计师优化和提升设计方案，具有较强的可操作性。

The work aims to study the evaluation method of sustainable design of outdoor classified garbage cans from the perspective of sustainable design, in order to better balance the comprehensive satisfaction of users, enterprises, environment, resources and other needs. Through field observation and interview research, multiple needs were collected, and the satisfaction survey data of preliminary needs were collected by the two-factor five-order Likert questionnaire. Kano model was adopted to analyze and calculate the need sensitivity and screen the needs. By taking the screened needs and corresponding sensitivity as the evaluation index and index weight, the sustainable design evaluation index system was constructed. Combined with the grey correlation evaluation algorithm, the schemes of outdoor classified garbage cans were evaluated and verified. 12 design schemes were used as the evaluation cases and ranked comprehensively, and then the comprehensive optimal scheme was further optimized by single index advantage. The practice results show that the sustainable design evaluation method of outdoor classified garbage cans based on multi-satisfaction can effectively evaluate the sustainable design quality of outdoor classified garbage cans, help designers optimize and improve the design scheme, and have strong operability.
