质量功能展开(QFD),即质量屋的建造,是在整合产品生命周期内对产品功能质量进行分析、展开的理论方法。综合考虑客户要求、技术要求、市场状况以及其相互间的作用关系对产品质量、功能的影响。着重阐述质量屋的生成过程。并以洗衣机为例,建立分析、评价模型,构造相关要素矩阵,形成洗衣机的设计流程以及方法。 Quality Function Deployment (QFD), that is, the construction of quality housing, is a theoretical method for analyzing and expanding the functional quality of products during the integrated product life cycle. Comprehensive consideration of customer requirements, technical requirements, market conditions and their interaction between the impact on product quality, function. Focus on the production of quality housing process. Taking the washing machine as an example, this paper establishes the analysis and evaluation model, constructs the matrix of relevant factors, and forms the design flow and method of the washing machine.
