I have an experiment set up for a DOE analysis with 5 factors, with 4 factors having 3 levels, and 1 factor having 5 levels.

The 1 factor having 5 levels cannot be made smaller, each of the 5 levels is a different model of a card we are testing and it is not numerical.

The other 4 can be made into 2 levels, as they are numerical and evenly spaced.

Also, the experiment is not hard to run, it is simulated on a computer - I can run about 400 cases within an hour. However, the point of this is to try to find a way to run as little tests as possible and to achieve a model that can accurately predict the result.

What sort of analysis should I use? Factorial? Taguchi?

Thanks! I am very inexperienced in DOE and Minitab.
