Syntax
- This PC software is developed for Windows XP/Vista/7/8/10 environment, 32 and 64-bit versions. This tool was originally produced by Stat-Ease, Inc. Also the program is known as 'Design-Expert', 'Design-Expert Wiley', 'Design-Expert Trial'. Design-Expert® lies within Photo & Graphics Tools, more precisely 3D Design.
- Among various design approaches, the Box-Behnken design was used to optimize and evaluate main effects, interaction effects and quadratic effects of the process variables on the particle size, entrapment efficiency and practical yield. This design is suitable for exploring quadratic response surfaces and constructing second order polynomial models.
- The Box-Behnken design is an independent quadratic design in that it does not contain an embedded factorial or fractional factorial design. In this design the treatment combinations are at the midpoints of edges of the process space and at the center. These designs are rotatable (or near rotatable) and require 3 levels of each factor.
- Unlike 3-level full factorial design, central composite design, and Box-Behnken design, there is no need to use a central point for any parameter in case of present model 29,30,31. Central point is needed when large numbers of experimental runs are required. Hence, 2-level factorial design can be used for the optimization, without utilizing.
dBB = bbdesign(n)
[dBB,blocks] = bbdesign(n)
[...] = bbdesign(n,param,val)
Description
dBB = bbdesign(n) generatesa Box-Behnken design for n factors. n mustbe an integer 3 or larger. The output matrix dBB is m-by-n,where m is the number of runs in the design. Eachrow represents one run, with settings for all factors representedin the columns. Factor values are normalized so that the cube pointstake values between -1 and 1.

[dBB,blocks] = bbdesign(n) requestsa blocked design. The output blocks is an m-by-1vector of block numbers for each run. Blocks indicate runs that areto be measured under similar conditions to minimize the effect ofinter-block differences on the parameter estimates.
