Digital twins bring value to mechanical and aerospace systems by speeding up development, reducing risk, predicting issues and reducing sustainment costs. Realizing these benefits at scale requires a structured and intentional approach to digital twin conception, design, development, operation and sustainment. To bring maximal value, a digital twin does not need to be an exquisite virtual replica but instead must be envisioned to be fit for purpose, where the determination of fitness depends on the capability needs and the cost-benefit trade-offs.
数字孪生通过加快开发速度、降低风险、预测问题和降低维护成本，为机械和航空航天系统带来价值。要大规模实现这些效益，需要对数字孪生的概念化、设计、开发、运营和维护采取结构化且有针对性的方法。为了带来最大价值，数字孪生不需要是精确的虚拟复制品，相反，必须设想它是适合特定用途的，其中适用性的确定取决于能力需求以及成本效益权衡。
