DoE Optimise a ratio of two factors
I currently have a material made using 100% of expensive factor A. I want to replace some of A with cheaper factor B but I'm not sure what the optimal ratio would be to achieve the same performance when using 100% of factor A. I believe I need a minimum of 50% factor A. How could I design a series of experiments using JMP (pro 18) that try to optimise this ratio so I can remove most of the expens...
