This paper deals with random effects and variance components for the split-plot design, which has been recognized as a valid plan for a robust design approach in the technological field. Our aim is to analyze this experimental design from two points of view: the theoretical basis of a split-plot is first evaluated as a specific and valid experimentation for the robust-design, paying attention to the interactions between control and environmental variables as random effects. The second point relates to the split-plot and the optimization in a multiple response case, by involving just one objective function, which considers the different contribution of the fixed and random parts for each estimated surface. The proposal is also analyzed through a case study.

Abstract
This paper deals with random effects and variance components for the split-plot design, which has been recognized as a valid plan for a robust design approach in the technological field. Our aim is to analyze this experimental design from two points of view: the theoretical basis of a split-plot is first evaluated as a specific and valid experimentation for the robust-design, paying attention to the interactions between control and environmental variables as random effects. The second point relates to the split-plot and the optimization in a multiple response case, by involving just one objective function, which considers the different contribution of the fixed and random parts for each estimated surface. The proposal is also analyzed through a case study.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
