It's proved that using the above asymmetric loss function, Taguchi's ideas of parameter design still works: first reduce the variance, and then reduce the bias.
说明了在非对称的二次损失函数下，也可以采用田口玄一减小质量损失的思想：先进行稳健性设计减小波动，再进行灵敏度设计减小偏差。
In the paper, Asymmetric quadric loss function is put forward under Normal assumption, adjustment parameter is defined, and its best value is calculated which minimizes the total quality lose.
本文讨论了在n维非对称的质量损失函数下，调整参数设计的可行性，求出了质量损失的最小解。
