QFD和AHP相结合的产品质量多维评估模型

A QFD and AHP combined multiple dimensional evaluation model for product quality

摘要:

产品设计是一个将用户需求自顶向下转换为各级产品性能要求的复杂过程,在每一级设计过程中都需要对多个可选项进行评估以便选择出满足性能要求的产品．为了得到每个产品可选项较为客观的质量权值,首先将产品设计描述为产品结构与或树模型,基于该模型提出一种QFD和AHP相结合的产品质量多维评估模型,通过QFD将用户需求转换为各级产品的质量准则,采用AHP对各级产品的多个可选项的质量进行评价,两步结果相结合计算得出产品的各个可选项相对用户需求的质量权值．最后通过一个仿真实例对评估模型进行了验证．仿真实例验证了所提出评估模型的可行性和有效性．

Abstract:

To get the objective quality weight values for the alternates of each product, first, the product design is formulated as a product and／or tree model. Next, based on this model, a QFD and AHP combined multiple dimensional evaluation model for product quality is proposed. In the evaluation model, the customer requirements are transformed into the quality criteria of each level of a product by QFD and the quality of the alternates for each level of a product is evaluated by AHP, then their results are combined to compute the quality weight values for the alternatives of each level of a product. Finally, the evaluation model is demonstrated by a simulated example.
