Taguchi Dynamic Problem

[Krishnan CL]

I am planning an experiment for optimizing single response using signal response taguchi energy transfer function. I would like to know.

01. Is it always true that there exists one set of unique control factors for all signal levels to reach overall optimum and why ?

02. Is it possible to find different combinations of control factors for different signal levels with which better optimum can be reached ?

Thanks for the answers.

Hi If there are uniqe answers for each level of each signal factor , then the designer's attempt to overall optimization is aborative. His professional job is optimize the product despite of several signal factors good luck --- On Thu, 9/13/12, Krishnan CL <clkri...@gmail.com> wrote:

Dear Krishnan,
I agree with the answers/explanations given by MOHAMMADREZA NABATCHIAN  earlier. Consider the case example (Airbag Deployment Pressure) below. You may indeed have different OPTIMUM designs at different levels of signal (M1, M2, etc.). But, since in application, you have no control as to the levels of the signal factor, you must look for a factor level combination (OPTIMUM DESIGN) that is good for the entire range of the signal level.

Dear sir,

I m a student and I have got a project on Crank noise reduction in 2 wheeler in HONDA as a major project in final year Engineering and I m using Taguchi approach to solve that noise factor so plz suggest me

I think it depends on what you are working on.

 

In a dynamic situation  you must first establish the ideal function for each response variable as it varies across the operating range of signal levels.  The goal is to find a combination of control factors that when tested in the presence of noise brings the system performance as close to ideal as possible with greatly reduced variation.  You do not have new control factors or noises introduced at different signal levels.

 

If you have different optimal combinations of control factors for various signal levels then you do not have a dynamic problem in the Taguchi sense.

 

It all depends upon the foundational physics of the problem you are addressing.  Hope this helps.
