Digital twin has the potential to be an important concept for achieving smart manufacturing. However, there remains a lot of confusion about the concept and how it can be implemented in real manufacturing systems, especially among small-to-medium-sized enterprises. This paper synthesizes the different perspectives that have been reported on the digital twin to identify the key characteristics that must be understood when developing a digital twin for a specific use case. Example applications are provided and the need for a standardized framework, such as the one under development as ISO 23247 (Digital Twin Manufacturing Framework), is motivated. This framework can enable context-dependent implementations and promote composability and reusability of digital twin components.
数字孪生有潜力成为实现智能制造的一个重要概念。然而，对于这一概念以及如何在实际制造系统中实施，仍然存在很多困惑，尤其是在中小企业中。本文综合了已报道的关于数字孪生的不同观点，以确定在为特定用例开发数字孪生时必须理解的关键特征。文中提供了示例应用，并提出了对标准化框架的需求，例如正在制定的ISO 23247（数字孪生制造框架）。该框架可以实现与上下文相关的实施，并促进数字孪生组件的可组合性和可重用性。
