【摘要】：在大规模定制以及绿色设计环境下，如何正确、有效地获取绿色产品的客户需求信息是设计出客户满意产品的关键。然而，由于客户需求表达的复杂性和不规范性，使得绿色产品客户需求的获取以及处理较为困难，严重影响了产品设计的准确性和设计的效率。针对以上问题，本文提出一种基于知识重用的绿色产品客户需求处理与转换方法的研究课题。文中首先对客户需求及知识重用的国内外研究现状进行了综述，指出国内外现有研究方法的不足，并阐述了本研究的必要性。利用本体论方法对绿色产品客户需求进行知识表达，建立了基于本体的绿色产品客户需求知识模型。结合绿色产品客户需求的具体特点以及知识检索的一般流程，建立了基于本体的语义知识检索系统模型；通过基于领域本体的查询扩展和基于语义相似度的知识检索实现了绿色产品客户需求知识的检索和获取，对获取到的客户需求知识进行决策优化并重用，得到最优客户需求集合。利用因果分析法实现绿色产品客户需求向绿色设计工程参数的转换；基于敏感性分析方法以及递阶质量屋方法，提出了一种改进的绿色设计工程参数权重确定方法；以客户满意为最终目标，对得出的绿色设计工程参数进行客户满意度的评价，，保证绿色设计的正确实施。最后，以冰箱产品为例，说明了该方法的具体实施过程。
[Abstract]:In the environment of mass customization and green design, how to get the customer demand information of green product correctly and effectively is the key to design customer satisfaction product.However, due to the complexity and non-standardization of customer demand expression, it is difficult to obtain and deal with the customer requirements of green products, which seriously affects the accuracy of product design and design efficiency.In view of the above problems, this paper presents a research topic of green product customer demand processing and transformation method based on knowledge reuse.In this paper, the domestic and foreign research status of customer demand and knowledge reuse is summarized, the deficiency of existing research methods at home and abroad is pointed out, and the necessity of this research is expounded.The ontology method is used to express the customer demand of green product, and an ontology based knowledge model of green product customer demand is established.Combined with the specific characteristics of green product customer demand and the general process of knowledge retrieval, a semantic knowledge retrieval system model based on ontology is established.Through query extension based on domain ontology and knowledge retrieval based on semantic similarity, the retrieval and acquisition of green product customer demand knowledge are realized, and the obtained customer demand knowledge is optimized and reused.Get the optimal customer demand set.Based on the sensitivity analysis method and the hierarchical quality house method, an improved method for determining the weight of green design engineering parameters is proposed.Taking customer satisfaction as the ultimate goal, this paper evaluates the green design engineering parameters to ensure the correct implementation of green design.Finally, taking the refrigerator product as an example, the concrete implementation process of the method is explained.
