E80 Group's discrete-event simulation software called SmartDesigner, is modeled and integrated according to the intralogistics management principles required by the customer. It is an essential tool for designing future operating scenarios and identifying the right intralogistics solution for new and existing plants. This empowers us to maximize process optimization in plants where many variables are in play, verifying flows, identifying potential criticality issues well in advance, and validating the most appropriate control logics with 95% reliability. Whether applied to brownfield or greenfield sites, discrete-event simulation is decisive in developing smart factories: integrated and automated factories that are flexible enough to adapt to the needs of the market and respond rapidly to possible changes.
