ABSTRACT

In this note, we deal with a design problem for determining the levels of noise factors in the Taguchi method. Recently, Ree(2009) proposed a new method to determine the levels of noise factors that is dependent on the distribution of the noise factors. We discuss the original suggestion from Taguchi method, propose a way to compare the two methods and investigate the performance(mean square error) of two proposals by examples.

Key Words: Taguchi method;smaller-the-better;noise factor;mean square error;
