“…The I4.0 characteristics and implementation challenges were studied by Kolberg and Zühlke (2015); Oztemel and Gursev (2020), Frank et al (2019) and Kumar et al (2021b) developed an implementation model/framework, while some others studied implementation readiness (Basl, 2017; Hizam-Hanafiah et al , 2020; Kiel et al , 2017; Mogos et al , 2019). 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.…”
