Embedding ergonomics in the design process is often delayed as it requires building physical prototypes and human subject data collection. This causes retrofitting or expensive late design changes which increase overall cost and time-to-market. This paper presents a computational design methodology that employs Digital Human Modelling (DHM) research and the surrogate modelling technique to integrate ergonomics early in design. The goal of this methodology is to provide a proactive ergonomics assessment toolset that allows designers to identify the effects of design variables on human performance, computationally. In this research, a design space exploration study was conducted to evaluate the ergonomics of a concept aircraft cockpit model built based on a set of flight deck layout variables. Variability in the pilot's anthropometry was added through accommodating the extremities in population-based on computational human manikins. A genetic algorithm with the surrogate model was used to search the concept variants that meet ergonomics objectives. The results show that the proposed proactive ergonomics approach allows designers to explore the design space and evaluate trade-offs between the competing design objectives early in design. Our computational ergonomics approach, based on the cockpit packaging study, demonstrates the advantages of the DHM based surrogate modelling during product conceptualisation.

人体工程学在设计过程中的嵌入通常会被延迟，因为这需要构建物理原型和人类受试者数据收集。这会导致改型或昂贵的后期设计变更，从而增加了总体成本和上市时间。本文提出了一种计算设计方法论，该方法论运用了数字人体模型（DHM）研究和替代建模技术，以在设计早期就整合了人体工程学。这种方法的目标是提供一种主动的人体工程学评估工具集，使设计人员能够通过计算来识别设计变量对人类绩效的影响。在这项研究中，进行了一项设计空间探索研究，以评估基于一组驾驶舱布局变量而构建的概念飞机驾驶舱模型的人体工程学。飞行员的可变性 通过计算人体模型，通过适应人群的肢体来增加人体测量学。使用具有替代模型的遗传算法来搜索满足人体工程学目标的概念变体。结果表明，所提出的主动人体工程学方法使设计师能够在设计初期探索设计空间并评估竞争设计目标之间的权衡。我们基于驾驶舱包装研究的计算人体工程学方法，证明了在产品概念化过程中基于DHM的替代模型的优势。结果表明，所提出的主动人体工程学方法使设计师能够在设计初期探索设计空间并评估竞争设计目标之间的权衡。我们基于驾驶舱包装研究的计算人体工程学方法，证明了在产品概念化过程中基于DHM的替代模型的优势。结果表明，所提出的主动人体工程学方法使设计师能够在设计初期探索设计空间并评估竞争设计目标之间的权衡。我们基于驾驶舱包装研究的计算人体工程学方法，证明了在产品概念化过程中基于DHM的替代模型的优势。
