This paper considers the construction of mixed-level supersaturated split-plot designs (SSSPDs) which are very useful in screening situations where the number of factors is larger than the number of available observations and several of these factors have levels that they are hard to change. As a benchmark of obtaining optimal SSSPDs, lower bounds to our proposed designs are established. Illustrative examples are presented supporting our constructed designs.

混合水平过饱和裂区设计的构建

本文考虑了混合水平过饱和裂区设计 (SSSPD) 的构建，它在筛选因子数量大于可用观测值数量的情况下非常有用，并且其中一些因子具有难以改变的水平. 作为获得最佳 SSSPD 的基准，我们提出的设计的下限被建立。展示了支持我们构建的设计的说明性示例。
