Robust Parameter Design Method for Multilevel Control Factors with Continuous Noise Factors

Robust parameter design is a central technique of the Taguchi method, wherein parameters are designed such that output fluctuations are reduced even when the environmental and operating conditions change marginally. Generally, it is necessary to level the noise factor however this is often difficult to assign. It is sometimes possible to passively measure the value of the noise factor that is, when its value of the noise factor can be observed as a covariate.
