Above is a representation of a classic Box-Behnken (BB) design for 3 factors.

Numeric Factors: How many continuous numeric factors are involved in theexperiment?

The hybrid designs in Design-Expert software are from Roquemore’s paper. They are hard coded in our design catalog; i.e. The design points are read in, not generated. The particular 3, 4 and 6 factor designs are D311A, D416B and D628A. If you sort the design by standard order you get the designs layout in Roquemore’s paper.

Categoric Factors: How may discrete or categoric factors are involved in theexperiment?
Note
Box Behnken Doe
For BB’s the number of runs required for the numeric factors will bemultiplied by the number of categoric combinations. If two categoric factorshaving three levels each are added to this design the number of runs will bemultiplied by nine. Consider optimal designs when you have both numeric andcategoric factors.
Blocks: Some Box-Behnken designs can be blocked. The number of blocksdepends on the number of factors. If you need blocks in your design and the BBdesign cannot do what you need, switch to an optimal design.

Center Points: By default there will be some center points in a BB design,the number varies somewhat with the number of factors and blocks. Adding morecenter points is okay. Removing center points will adversely affect the design’sprecision capability.
