“…Different aspects related to the I4.0 regime, such as maturity models (Caiado et al , 2021), sustainability functions (Ghobakhloo, 2020), sustainability aspects (Bai et al , 2020; Machado et al , 2019; Müller et al , 2018), relation/integration with other industrial practices (Davis et al , 2020; Javaid et al , 2021; Tortorella et al , 2019), supply chain (Hofmann et al , 2019; Tiwari, 2020), possible impacts (Kumar et al , 2020b; Ulusoy et al , 2021), facility layout (Ficko et al , 2021), robotic collaborations (Dobra and Dhir, 2020; Goel and Gupta, 2020; Inkulu, 2021), human factors and ergonomic analysis (Laudante, 2017; Neumann et al , 2021) and others are also highlighted in the literature. Recently (Kumar et al , 2021c) proposed a labeling system and comparative index for comparing the automation levels in two or more I4.0 systems. Schlechtendahl et al (2015) rightly remarked that transforming the existing stock of production systems into I4.0 compatible units would be a viable option to adopt the concept of smart factories.…”
