Robust Design - Productivity during Design & Development


Robust Design is an engineering methodology for improving productivity during design & development so that high quality products can be produced at low cost.


Robust Design is an engineering methodology for improving productivity during design & development so that high quality products can be produced at low cost.


Robsut design optimization is systematic and efficient way to meet the challenge design optimization for performance, quality & cost. 

It is capable of

Making product performance insensitive to raw material variation, thus providing scope for  the use of lower grade alloys, 
Making designs robust against manufacturing variation, thus reducing material cost for rework & scrap,
Making the design least sensitive to the variation in operating environment.

It uses a new structured development process so that design engineering time is used more productively.

The Robust Design method uses a mathematical tool called Orthogonal Arrays to study a large number of decision variables with a small number of experiments. It also uses a new measure of quality called signal-to-noise (S/N) ratio to predict the quality from the customer's perspective.
