## Taguchi’s two stage optimization procedure

- SN metrics
- compromise between Mean and Standard Deviation can be considered a problem in decision making
- Does Non-linearity of SNN metric (societal loss function) suggests a decision analysis perspective?

- SN metrics

- Taguchi’s (SNN) metric (societal loss)
- Risk Averse for Mean
- Risk Prone for Standard Deviation
- Typically standard deviation attribute dominates over mean attribute ? Inherent aggressiveness of the SNnominal for minimization of standard deviation
