抽象的。本文介绍了有关人类解决参数设计任务的能力的实验结果。特别是，研究重点是设计变量和问题规模（设计变量的数量）之间的耦合如何影响参数设计问题的解决。对人类受试者进行了一项实验，他们通过简单的图形用户界面解决了参数设计任务。可以确定的是，对于只有两个输入和两个输出的参数设计任务，耦合对受试者解决问题的效果只有中等程度的影响。随着变量数量的增加，变量之间的耦合效应对求解过程和完成时间产生巨大影响。随着问题规模从 2×2 增加到 5×5，人类解决耦合参数设计问题的时间呈几何级数增长。这些结果是在人类认知的信息处理模型的背景下讨论的。探讨了对当前设计理论和方法的影响。
Abstract. This paper presents experimental results regarding human abilities to solve parameter design tasks. In particular, the investigations focus on how the solution of parameter design problems is affected by coupling among the design variables and the scale of the problem (number of design variables). An experiment was conducted with human subjects who solved parameter design tasks through a simple graphical user interface. It is established that, for parameter design tasks with only two inputs and two outputs, coupling had only a moderate effect on the subjects' solution of the problem. As the number of variables increases, the effect of coupling among variables has a drastic effect on the solution procedures and the completion time. The time for a human to solve a coupled parameter design problem rises geometrically as problem size rises from 2×2 to 5×5. These results are discussed in the context of information processing models of human cognition. The implications for current design theories and methodologies are explored.
