Streszczenie:
In the paper we consider a situation when split-split-plot experimental designs are incomplete due to both whole plot treatments and subplot treatments only. With respect to the sub-subplot treatments the presented designs are always orthogonal. Additionally one of the whole plot treatments and one of the subplot treatments are treated as standards.
To construct the final three-factor designs with nested treatment structures we can use two different or the same block designs from the class of orthogonally supplemented PEB block designs with at most (m+1)– efficiency classes. We present also algebraic and statistical properties of the generating designs and the resulting from the construction method split-split-plot designs as well as a numerical example.
