“…Da Silva et al [7] present a systematic literature review on innovative issues related to I4.0 in terms of energy efficiency. It should be noted that regardless of the classifications proposed in the literature, common technological elements of the I4.0 concept can be distinguished, such as cyber-physical systems (CPS) [8][9][10][11][12][13], digital twins (DT) [14], artificial intelligence (AI) and neural networks [15]; the Industrial Internet of Things (IIoT), direct communication between machines (M2M), the Internet of Services [16,17], and the use of large amounts of data-Big Data and analytics [18,19]; methods of collecting and processing large amounts of data, including the use of cloud-based activity [20][21][22][23]; horizontal/vertical software integration [24,25]; collaborative and autonomous robots [26][27][28]; simulation and prognostic techniques [29][30][31]; additive manufacturing [32,33]; mass customisation [34,35]; augmented reality (AR) and virtual reality (VR) technologies [36][37][38]. Similar elements of new technological solutions are also indicated by Wolniak et al [39] and Helo and Hao [40].…”
