“…Cyber-based design for additive manufacturing using artificial neural networks for Industry 4.0 (Elhoone et al, 2020) Intelligence Sustainable industrial systems within kernel density analysis of artificial intelligence and industry 4.0 (Soebandrija et al, 2018) Modelling: Modelling includes operational research techniques that have long been used in manufacturing (Greasley, 2005, Smith et al, 1994 to "understand the states, conditions and behaviors of the systems under control and those of peer systems by interpreting and correlating data gathered from sensors and peer systems" (Lin et al, 2015, p. 29). Virtual models built from sensor data provide valuable insights into existing or planned systems and thus enable better decision-making during activities such as shop floor layout optimisation (Eklin et al, 2009), production process control (Iassinovski et al, 2008) and inventory control (Rezg et al, 2005).…”
