This living digital model is fed by continuous streams of real-time sensor data, integrating learnings back into the physical product. As Rajkumar Buyya, Redmond Distinguished Professor at the University of Melbourne [1] explains:
"An automotive digital twin continuously learns and updates itself from multiple sources including sensors, instrumentation, actuators, maintenance logs, schematics, operator feedback and environmental conditions to mirror the life of its corresponding physical entity."
But digital twins extend beyond individual vehicles to model automakers‘ entire production environments. This includes assembly lines, robotic arms, and even workers interacting seamlessly with the latest Industry 4.0 systems.
The result? Automakers can test countless "what if" scenarios to optimize manufacturing. And proactively predict and prevent issues before costly physical disruptions.
Now let‘s explore the top ways automakers harness digital twins to drive operational excellence.
