Digital twins: A brief overview of applications, challenges and enabling technologies in the last decade
The concept of Digitals Twins (DTs) is an evolving idea, which is becoming the center of attention for the industry and the scientific community. It can be described as the pairing of the digital and the physical, interconnected for data sharing. DT is a key enabler for Industry 4.0, especially on the digitalization and visualization processes. Even though the idea of DT has been defined thoroughly throughout the recent years, there are still many different interpretations which are the result of different viewpoints of the involved professionals. The digitalization process requires huge amounts of data, which is generated, collected, handled and processed by various sources as well as digital twins themselves, thus offering new challenges that need to be addressed. In this paper, we attempt to i) assess the current state of digital twins, ii) describe the terms digital model and digital shadow as they are often misused as synonyms and iii) review the concepts of Internet of Things (IoT) and Industry 4.0 and discuss how these are connected. Moreover, some applications of DTs and their enabling technologies will be presented.
