In Nanjing, Siemens has built a digital native plant. Even before the first concrete was poured, the plant’s performance was simulated with a digital twin. This helped to avoid small and big planning errors, which in the past would cost a lot of money and – often much worse – a lot of time.
For example, the planning team was able to spot a painting machine without proper ventilation during a virtual inspection. In the real world this would have a caused a lot of hassle. Yet all it took was a few drag and drops during the design phase to put it in a more suitable spot.
In daily operations, the digital twin is now used to optimize the plant through a constant feedback loop between ongoing production and simulation. The benefits of this digital factory are measurable: Manufacturing capacity increased by 200% and productivity by 20%
