质量功能展开（QFD）是产品规划中的重要工具，有助于提高客户满意度，缩短产品设计和开发时间。在质量功能展开过程中，确定顾客需求的重要性权重是一个至关重要的步骤。采用层次分析法（AHP）对各指标的重要性进行加权.然而，由于存在的模糊性和不确定性的重要性，归因于判断的客户需求，在传统的层次分析法，清晰的两两比较似乎是不够的，不精确的捕捉客户需求的重要程度。本文将模糊数引入到层次分析法的两两比较中。提出了一种基于模糊标度的层次分析法来确定客户需求的重要性权重。该方法可以改善基于传统层次分析法的客户需求排序的不精确性。最后，以自行车挡泥板设计为例，说明了所提出的方法。
Quality function deployment (QFD) is an important tool in product planning that could contribute to increase in customer satisfaction and shorten product design and development time. During the QFD process, determination of the importance weights of customer requirements is a crucial and essential step. The analytic hierarchy process (AHP) has been used in weighting the importance. However, due to the vagueness and uncertainty existing in the importance attributed to judgement of customer requirements, the crisp pairwise comparison in the conventional AHP seems to be insufficient and imprecise to capture the degree of importance of customer requirements. In this paper, fuzzy number is introduced in the pairwise comparison of AHP. An AHP based on fuzzy scales is proposed to determine the importance weights of customer requirements. The new approach can improve the imprecise ranking of customer requirements which is based on the conventional AHP. Finally, an example of bicycle splashguard design is used to illustrate the proposed approach.
