虽然广泛的建模--物理的和虚拟的--对于第一次开发正确的产品是必不可少的，但虚拟模型和物理模型的并行使用引起了两个相互关联的问题：缺乏对物理原型的修订控制；以及设计者需要手动检查、测量和解释对虚拟或物理模型的修改，以便随后更新另一个。数字双胞胎模式在产品生命周期的后期解决了类似的问题，虽然这些数字双胞胎或“双胞胎”过程已经显示出显著的价值，但到目前为止，关于它们在早期设计阶段的实施工作很少。本文探讨了在早期设计中使用数字孪生技术的概念，包括数字孪生技术的介绍、实施的机会和挑战、早期阶段孪生技术的结构介绍，以及通过两个实施案例进行评估，从而提高了产品的理解、性能和设计周期时间和成本。
ABSTRACTWhile extensive modelling - both physical and virtual - is imperative to develop right-first-time products, the parallel use of virtual and physical models gives rise to two interrelated issues: the lack of revision control for physical prototypes; and the need for designers to manually inspect, measure, and interpret modifications to either virtual or physical models, for subsequent update of the other. The Digital Twin paradigm addresses similar problems later in the product life-cycle, and while these digital twins, or the “twinning” process, have shown significant value, there is little work to date on their implementation in the earlier design stages. With large prospective benefits in increased product understanding, performance, and reduced design cycle time and cost, this paper explores the concept of using the Digital Twin in early design, including an introduction to digital twinning, examination of opportunities for and challenges of their implementation, a presentation of the structure of Early Stage Twins, and evaluation via two implementation cases.
