摘要
田口玄一所建立的产品质量损失模型是以绝对质量偏移为基础,针对的是单一的质量指标。而实际生产中,很多分质量指标往往共同对产品质量产生影响,因此需要在产品质量模型中考虑到各个分质量指标的互作用。本文以田口玄一的质量损失模型为基础,研究了以相对质量偏移为元素的包含多个分质量指标的产品质量模型,并将其推广到3阶以上。接着,对产品质量模型进行化简,推导出其简化的产品质量损失公式(质量损失模型的多元形式),并对模型误差进行了理论分析。最后提出了在生产中建立多元产品质量损失模型的工作流程,并以一个实例对该过程进行了说明。
The quality loss model of Taguchi was based on one index of absolute quality deviation. In actual production process, the product quality is usually influenced by several quality indexes, so the interaction of the quality indexes should be considered. Based on the quality loss model of Taguchi, the product quality model which based on several indexes of relatively quality deviation was studied. After deducing a simplified formula, a new simplified product quality model （a multivariate quality loss model） was built and the error of it was also analyzed. Then, the work flow of the application of multivariate product quality model was described. Finally, the multivariate product quality model was applied to a manufacturing instance successfully.
