2. Finding the summit without a map

This optimization method is often summed up in this image. Without ever jeopardizing your production, you will gradually be able to direct them to the most efficient point.

It will therefore suffice to apply minute variations in parameters, at levels that can be described as homeopathic, and check the effect on the characteristics of the products manufactured. In any case, the programmed variations are insufficient to significantly degrade production.

You can rest assured that, even if these variations turn out to be negative, the result obtained will always be maintained at a level that allows the production to be marketed.

Experimentation will be based on the latest results obtained. The "programmed" point will be located symmetrically to the "worst" result. If you only have one variable, we won't even talk about...
