1956年，当人工智能(AI)被正式宣布为一个研究领域时，没有人会预测到它的描述、预测和处方能力将对我们的日常生活产生巨大的影响和影响。在人工智能不断进步的同时，过去十年见证了宽带和无处不在的连接的普及，(嵌入式)传感器收集描述性高维数据，以及大数据处理技术和云计算的改进。这些技术的共同使用导致了数字双胞胎的创建，即物理系统的人工智能虚拟复制品。数字双胞胎(DT)技术目前正在开发和商业化，以优化几个制造和航空工艺，而在医疗保健和医药领域，这项技术仍处于早期开发阶段。本文介绍了一项研究的结果，重点分析了数据转换的最新定义，调查了数据转换应具备的主要特征，并探索了当前正在开发的数据转换应用领域。然后提出了从这项研究中得出的设计影响：它们侧重于社会技术设计方面和DT生命周期。最后讨论了未来需要解决的未决问题和挑战。
When, in 1956, Artificial Intelligence (AI) was officially declared a research field, no one would have ever predicted the huge influence and impact its description, prediction, and prescription capabilities were going to have on our daily lives. In parallel to continuous advances in AI, the past decade has seen the spread of broadband and ubiquitous connectivity, (embedded) sensors collecting descriptive high dimensional data, and improvements in big data processing techniques and cloud computing. The joint usage of such technologies has led to the creation of digital twins, artificial intelligent virtual replicas of physical systems. Digital Twin (DT) technology is nowadays being developed and commercialized to optimize several manufacturing and aviation processes, while in the healthcare and medicine fields this technology is still at its early development stage. This paper presents the results of a study focused on the analysis of the state-of-the-art definitions of DT, the investigation of the main characteristics that a DT should possess, and the exploration of the domains in which DT applications are currently being developed. The design implications derived from the study are then presented: they focus on socio-technical design aspects and DT lifecycle. Open issues and challenges that require to be addressed in the future are finally discussed.
