Abstract Digital twin represents a fusion of the informational and physical domains, to bridge the material and virtual worlds. Existing methods of digital twin modeling are mainly based on modular representation, which limits guidance of the modeling process. Such methods do not consider the components or operational rules of the digital twin in detail, thereby preventing designers from applying these methods in their fields. With the increasing application of digital twin to various engineering fields, an effective method of modeling a multi-dimensional digital twin at the conceptual level is required. To such an end, this paper presents a method for the conceptual modeling of a digital twin based on a five-dimensional digital twin framework to represent the complex relationship between digital twin objects and their attributes. The proposed method was used to model the digital twin of an intelligent vehicle at the concept level.

基于集成五维框架和TRIZ函数模型的概念数字孪生建模

摘要 数字孪生代表了信息领域和物理领域的融合，连接了物质世界和虚拟世界。现有的数字孪生建模方法主要基于模块化表示，这限制了建模过程的指导。这种方法没有详细考虑数字孪生的组件或操作规则，从而阻碍了设计人员在他们的领域中应用这些方法。随着数字孪生越来越多地应用于各个工程领域，需要一种在概念层面对多维数字孪生进行建模的有效方法。为此，本文提出了一种基于五维数字孪生框架的数字孪生概念建模方法，以表示数字孪生对象及其属性之间的复杂关系。
