Abstract Computer experiments may involve not only continuous input factors but also nominal factors, discrete numeric factors, and ordinal factors. Most existing literature in designing computer experiments focuses only on continuous factors. Some works have further considered nominal factors, but the cases that also contain discrete numeric or ordinal factors are almost overlooked. In this work, we propose a new optimal design criterion that can accommodate all these types of factors. The proposed design is flexible in run size and number of factors, and can also achieve good space-filling properties in the full design space and in all possible low-dimensional projections.

设计具有多种类型因素的计算机实验：MaxPro 方法

摘要 计算机实验不仅可能涉及连续输入因子，还可能涉及名义因子、离散数值因子和序数因子。大多数现有的计算机实验设计文献仅关注连续因素。一些工作进一步考虑了名义因素，但几乎忽略了还包含离散数字或序数因素的情况。在这项工作中，我们提出了一个新的优化设计标准，可以适应所有这些类型的因素。所提出的设计在运行大小和因子数量方面具有灵活性，并且还可以在整个设计空间和所有可能的低维投影中实现良好的空间填充特性。
