Digital twins for flexible linking of live sensor data with real-time models

For taking most advantage of real-time sensor data, data has to be processed by a single or even by a chain of models. Digital Twins (DTs) provide software platforms to perform the processing also in real-time in contrast to earlier simulation studies. The step from IoT to a full exploitation of DTs solutions entails new challenges, such as the transformation of models into an updateable format, but also new features, such as the easier and flexible linking of different models through a streaming platform. We discuss this key challenges and features based on our example application for remote monitoring of ocean fruit transportation.
