Robustness Development and Reliability Growth: Value-Adding Strategies for New Products and Processes

Chapter 18. Developing System Robustness Using DOE

In this chapter we show how you can use traditional modeling experiments to improve system robustness. To do this you have to consider the effect of variations in the control factors and any external noise factors that you may have included in the experiment. Once you have a model that includes both control factors and noises, you can select favorable settings for the control factors to place performance on target with minimum variability.

Using System Models and Noise to Improve Robustness

First we cover the role of noises in your experiment strategy, building on the ideas presented in Chapter 7. To make a system more robust, you use noises to intentionally stress your system. This is normally ...
