摘要: 在分析了Taguchi平方型质量损失函数局限性的基础上,采用逆正态型的质量损失函数,建立了一般情形下多维质量属性的质量损失函数模型,对模型参数的确定及质量水平分析进行了讨论,举例说明了模型在制造决策中的应用。

Abstract: Based on the discussion about the disadvantages and limitations of traditional Taguchi's squared error loss function, the inverse normal loss function and the extensive quality loss function model with multiple quality attributes are introduced. How to get the parameters and analyze the quality level (risk function) are discussed. Some examples of applying the model in manufacturing system decision making are given.
