面向客户需求是企业在当前竞争激烈的市场环境下成功的关键。本文提出了一种快速响应客户需求的产品优化设计方法，通过基于模糊相似理论的需求信息模糊聚类方法，对具有模糊性和多样性的原始客户需求信息进行精简分类处理，以获取客户需求集合；然后构建了一种综合联合分析法（CA）和质量功能展开（QFD）的全新CA-QFD需求转化方法，从客户需求到产品设计属性进行精确转化，并通过对实例产品的优化设计，实现快速响应客户需求；最后，通过锻压机主工作液压缸的优化设计实例，验证了本文方法的可行性和适用性。

In the current highly competitive market environment, a critical success factor for enterprises is the ability to rapidly respond to customer requirements (CRs). This paper proposes a novel method for rapid response to CRs in product optimization design via fuzzy clustering and conjoint analysis-quality function deployment (CA-QFD).The proposed approach has two key characteristics. The first is classifying original complex CR data as a standard CR dataset by fuzzy clustering method. The second is the new CA-QFD transformation method integrating conjoint analysis and traditional QFD, which can accurately transform CRs into product design attributes. Finally, an example for product optimization design by forging a machine's main hydraulic cylinder is carried out to demonstrate the validity of the proposed method.
