Industrial Internet of Things: Digital Twins

The Industrial Internet of Things (IIoT), contributes to the industrial sector by expanding its manufacturing processes with its modern devices and intelligent systems. Today, the industrial sector is in a race to increase the insertion of technologies in its supply chain and production activities. For this, IIoT uses tools like the Internet of Things (IoT), Big Data, Could Computing, Artificial Intelligence and, recently, the Digital Twins, theme of this article. This study intends to explore and discuss the particularities of Digital Twins and their fundamental characteristics for the development of their reference architecture model, such as their internal structure, runtime environment, semantic orientation, among other aspects.
