质量功能展开(QFD)是在处理新产品开发过程中以客户为导向的方法，以最大限度地提高客户满意度。在新产品开发的QFD活动过程中，确定设计要求(DRS)和零件特性(PC)的满足水平是非常重要的决策问题。不同于现有文献主要关注决策树的确定，本文提出了模糊线性规划模型，在满足决策树对顾客满意度贡献水平的要求下，确定顾客满意度的满足程度。此外，考虑到设计风险，本文将失效模式和影响分析(FMEA)引入到QFD过程中，并将其约束处理在模型中。为了处理产品开发过程的模糊性，对FMEA和QFD都使用了模糊方法。通过数值算例对所提出的模型进行了说明，以验证其在实践中的适用性。(C)2007 Elsevier Inc.保留所有权利。
Quality function deployment (QFD) is it customer-driven approach in processing new product developments in order to maximize customer satisfaction. Determining the fulfillment levels of design requirements (DRs) and parts characteristics (PCs) is ail important decision problem during QFD activity processes for new product development. Unlike the existing literature, which mainly focuses oil the determination of DRs, this paper proposes fuzzy linear programming models to determine the fulfillment levels of PCs under the requirement to achieve the determined contribution levels of DRs for customer satisfaction. In addition, considering the design risk, this paper incorporates failure modes and effect analysis (FMEA) into QFD processes, which is treated its the constraint in the models. To cope with the vague nature of product development processes, fuzzy approaches are used for both FMEA and QFD. The illustration of the proposed models is performed with it numerical example to demonstrate the applicability in practice. (C) 2007 Elsevier Inc. All rights reserved.
