数字孪生（DT）是工业4.0浪潮的主要概念之一。这个术语越来越多地用于工业和研究活动中;然而，科学文献并没有提供这个概念的唯一定义。本文旨在分析科学文献中DT概念的定义，追溯它从航空航天领域的最初概念化，到制造领域的最新解释，更具体地说，在工业4.0和智能制造研究中。DT提供系统沿着其生命周期的虚拟表示。然后，优化和决策将依赖于通过传感器实现的同步与物理系统实时更新的相同数据。本文还提出了欧洲H2020项目MAYA阐述的工业4.0制造DT的定义，作为对DT概念研究讨论的贡献。© 2017作者。由Elsevier B. V.出版，同行评审，由第27届柔性自动化和智能制造国际会议科学委员会负责。
The Digital Twin (DT) is one of the main concepts associated to the Industry 4.0 wave. This term is more and more used in industry and research initiatives; however, the scientific literature does not provide a unique definition of this concept. The paper aims at analyzing the definitions of the DT concept in scientific literature, retracing it from the initial conceptualization in the aerospace field, to the most recent interpretations in the manufacturing domain and more specifically in Industry 4.0 and smart manufacturing research. DT provides virtual representations of systems along their lifecycle. Optimizations and decisions making would then rely on the same data that are updated in real-time with the physical system, through synchronization enabled by sensors. The paper also proposes the definition of DT for Industry 4.0 manufacturing, elaborated by the European H2020 project MAYA, as a contribution to the research discussion about DT concept. © 2017 The Authors.
