Digital Twins - Improved Simulation
A digital twin is a technology that creates a virtual model of a physical object in the real world. Such technology is used to analyze the advantages and disadvantages of the model before the final product becomes available to the customer. To achieve the simulation, this modern technology uses computer-aided design (CAD). A digital twin is a more advanced version of the simulation where it is displayed in real time.
An excellent example of a digital twin is IBM's wind turbines, which provide important data about weather conditions and the output energy of the digital twin via sensors. The advantage of a digital twin simulation over other simulations is the ability to run multiple simulations where new insights can be fed back to the wind turbine.
As explained by IBM:
„Once informed with such data, the virtual model can be used to run simulations, study performance issues and generate possible improvements, all with the goal of generating valuable insights — which can then be applied back to the original physical object.“
They also explain that there are various types of digital twins a nit depends on the level of manufacturing:
Component twins/Parts twins - „The basic unit of digital twin, the smallest example of a functioning component.“
Asset twins - „When two or more components work together they let you study the interaction of those components“
System or Unit twins - „They provide visibility regarding the interaction of assets, and may suggest performance enhancements.“
Process twins - „The macro level of magnification, systems work together to create an entire production facility.“
