What is it that DOE can deliver and Simulation models cannot? What is it that Simulation models can deliver but DOE cannot? If simulation is used along with DOE, should DOE follow simulation or should simulation model be followed by DOE?

Hi VK,

Interesting point. Let me make an attempt.

DOE as the name suggests is a design where a lot of experimentation can be done wrt critical factors (x's) to arrive at a model (abstract)/equation which can deliver optimum output/performance.

Wheras simulation model (physical) represents a system, cabable of demonstrating the expected working of a system and which can be affected by external conditions unlike DOE model which remains static always.

To arrive at a simulation model initially, DOE equation can be the input. ie simulation is followed by DOE.But it may not be true in all cases. Wherever the results of simulation is seen and further improvement needs to be done in the model, DOE can then come into picture. Therefore, at a later stage of experiments and research work, the two can go hand in hand (following each other).

Over to others!
