• Which Run order I have to choose for my DoE?

  Hello,I want to perform a DoE in order to optimize an extraction method. My plan is to start with a screening of the main factors using Plackett Burman followed by a central composite design in order to do a response surface. Before making a Design tube I should choose a Run order (sort left to right, sort right to left, randomize...) and I do not know which run order I should choose for each of m...

• DOE center points vs. historical process targets

  I have a general question about the use of center points vs. historical process target values in DoE studies outlined in the scenario below: When deciding on the values to use for the high and low levels of factors in a DoE study, it was determined that the high/low levels that span the range of interest are not exactly symmetric around the current historical target values for some factors. When a...

• DOE Question: Contraints on Categorical Factors

  I would appreciate some advice...  I am running a screening experiment with strictly categorical factors and trying to identify the primary source of variation in my response.  The experiment involves material going into a surface process (known significant effect), followed by a bake (which needs to be done in batches to process everything through - any oven run to oven run variation?), followed ...
