摘　　要：针对QFD系统的内在模糊性,运用带有对称三角形模糊系数的模糊规划理论,提出了一种确定QFD系统参数的方法.并通过工程特性目标值的规范化,定义产品开发总成本函数、工程特性改进成本函数及改进成本系数等概念,建立了一个QFD规划模型.仿真结果表明,该模型能够帮助开发人员在不确定的、模糊条件下有效确定关联函数及自相关函数,优化顾客需求的满意水平,确定工程特性目标值,使新开发/改进的产品顾客满意度赶上或超过目标市场上的竞争企业,并满足开发预算约束.Aiming to the inherent fuzziness in quality function deployment (QFD) modeling, a new mathematic approach to identification QFD system parameters is presented using fuzzy optimization theory with symmetric triangular fuzzy number coefficients. By normalizing values of engineering characteristics, introducing new concepts of total development cost function, and improving cost function and cost coefficient of engineering characteristic, a program model for QFD is proposed. Simulation results shows that the model can help a design team to determine the relation functions between customer requirements and engineering characteristics, and correlation functions among engineering characteristics. It can also reconcile tradeoffs among the various customer satisfaction levels and identifies engineering characteristic target values for the new/improved product that meets a budget constraint and matches or exceeds the customer satisfaction of all competitors in the target market.
