摘　　要：分析了传统的质量屋设计过程存在的问题 ,提出了一个基于质量屋的产品设计过程的修正模型 ,并在充分考虑工程特性相关性对工程特性目标值和开发成本影响的基础上 ,以工程特性计划改进率变化范围和开发成本为约束函数 ,建立了一个基于质量屋的优化决策模型。该模型能充分利用质量屋中各部分的信息 ,权衡并优化质量屋中存在的各种矛盾和冲突 ,确定各个工程特性的目标值改进率 ,使所设计的产品在有限的资源约束下能最大限度地满足顾客需求。实例研究表明 ,该模型是有效的、可行的。Quality Function Deployment (QFD) is becoming a widely used customer-oriented approach in product development. Some methodological issues occurring in the conventional House of Quality (HoQ) are discussed, and then a new integrative decision model for selecting an optimal set of engineering characteristics is presented using a modified HoQ model. The modified HoQ prioritization procedure employs a multi-attribute decision method for assigning relationship ratings between customer requirements and engineering characteristics instead of a conventional relationship rating scale, such as 1-3-9. The proposed decision model can make full use of the information of every part in HoQ and offer optimized solution to the conflicts. It has been applied to the quality improvement problem of a motorcar as an illustrative example, and it is proved to be more reasonable and effective than the conventional methods.
