how to model components, data transference, and enablement
of tool utilization were presented in detail. With our cooperative
stakeholders, the team at NTNU will continue the work toward
realizing a fully functional digital twin of the Gunnerus, gradually
improving its accuracy. Continued development of use
cases will provide meaningful onboard decision support for the
crew of the Gunnerus. The other application is digital commissioning.
If we can feed different kinds of industrial data into a
simulator to create a digital twin system and use the simulator
to verify the concept, process, and control efficiency, it will definitely
reduce the development time and enhance production
efficiency. On the other hand, from a methodology point of
view, academic research can make use of simulated data to verify
effectiveness of the digital twin system. Once there are
enough real data available, the digital twin system can be updated
and serve as a digital replica of the physical system. As a
result, both industry and academia could take advantage of the
digital twin system to realize high-level applications.
