Gestamp's smart factory is based on the concept of the digital twin: a virtual model of a real factory that allows the production process to be optimised, thus becoming a valuable decision-making tool. Specifically, we have connected the physical elements of the plant via 5G, to capture and process in real time the data produced by such industrial equipment during its operation, through the near computing made possible by Multi Access Edge Computing (MEC). In this way, the data collected from the different industrial devices is processed to generate a more intelligent model, so that the representation of reality is as faithful as possible and allows scenarios to be validated and appropriate decisions to be taken.
