摘要
依据质量参数指标的共作用及互作用效应,对田口的基于绝对质量偏移的单变量质量损失模型进行扩展。在建立了基于相对质量偏移的多元质量损失模型的基础上,对于多元质量损失模型的核心问题(系数确定问题),提出了系数确定的容差法。
The quality loss model proposed by Genichi Taguchi in the early 1970s is based on the absolute deviation and it is a one-order model. However, in practice, product quality is affected by multiple factors with correlation. Thus, in this paper, the Taguchi's quality loss model is expanded in considering the rela- tive deviation of the quality indices. First, a 2-order multivariate quality model is presented. Then, this model is successfully extended to models with 3 or even higher order. The 2-order model is then simplified to build a multivariate quality loss model. A method is proposed to determinate the coefficients in the mod- el. Detailed procedure for the method is described.
