“…Among them, some frameworks reinterpret this structure, showing explicitly the (Kritzinger et al, 2018) distinction of a "Digital Shadow", a "Digital Model" and a full DTw (Cimino et al, 2019;Negri et al, 2020). Therefore, in general, this cluster collects basic architectures where the DTw is in parallel with the real system, discussing interfaces and interoperability with operations management systems such as MES, ERP and optimization modules (Cimino et al, 2019;Magalhães et al, 2022). Looking at the result within this cluster, we can assume that (Barbieri et al, 2021;Negri et al, 2020;Novák & Vyskočil, 2022;Ragazzini et al, 2021) present similar architectures, revisited with the specific inclusion of optimization modules or intelligent layers.…”
