D-Optimal Designs for Second-Order Response Surface Models with Qualitative Factors
نویسندگان
چکیده
Central composite design (CCD) is widely applied in many fields to construct a second-order response surface model with quantitative factors help increase the precision of estimated model. When an experiment also includes qualitative factors, effects between and should be taken into consideration. In present paper, D-optimal designs are investigated for models where interact with, respectively, linear effects, or 2-factor interactions quadratic factors. It shown that, at each level, corresponding consists three portions as CCD, i.e. cube design, axial center points, but different weights. An example about chemical study used demonstrate how obtained here may both more efficiently.

متن کاملOptimal Designs for Mixed-Effects Models with Random Nested Factors
The problem of experimental design for the purpose of estimating the fixed effects and the variance components corresponding to random nested factors is a widely applicable problem in industry. Random nested factors arise from quantity designations such as lot or batch and from sampling and measurement procedures. We introduce a new class of designs, called assembled designs, where all the nest...
