Borkowski}, country = {}, institution = {}, abstract = {The objective of the research is to study and compare response surface designs: Central composite designs (CCD), Box- Behnken designs (BBD), Small composite designs (SCD), Hybrid designs, and Uniform shell designs (USD) over sets of reduced models when the design is in a spherical region for 3 and 4 design variables. The two optimality criteria ( D and G ) are considered which larger values imply a better design. The comparison of design optimality criteria of the response surface designs across the full second order model and sets of reduced models for 3 and 4 factors based on the two criteria are presented.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {6}, number = {5}, year = {2012}, pages = {545 - 548}, ee = {https://publications.waset.org/pdf/11446}, url = {https://publications.waset.org/vol/65}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 65, 2012}, }
