December, 20208 IN MY V EWFIRST PRINCIPLE MODELS TO BOLSTER THE DIGITAL TWIN PANORAMABY RICHARD PORTER, PRINCIPAL ENGINEER, SIMULATION, YOKOGAWA AUSTRALIA PTY LTDWe would all like to know the future. Knowledge of the future changes how you act in the here and now. The problem is, how do we do it, how do we see the future? With the increasing requirement to achieve "more with less," the need to predict the future and act accordingly is greater than ever before. With the advancement of technology, it is now possible to answer the question, "How will my business respond to inputs in the next few hours, for the rest of today, tomorrow, and beyond?"Digital Twin technology has advanced to the point where it can now be used to answer these questions in a consistent and timely manner. Successful Digital Twin projects have shown that users can now have confidence in the technology and that the results are reliable. This is especially true for the process industry where Yokogawa has been providing products and solutions for over 100 years.The core technology that powers Yokogawa's successful Digital Twin projects is First Principles Mathematical modeling. A first principles model applies the laws of physics, such the movement and properties of materials, to calculate how a process behaves. A good example of first principles models can be seen in Car Driving computer games that took a great leap forward in realism when they began implementing physics engines to calculate the behaviour and response of vehicles.
