A Digital Twin is a virtual representation, a digitalized version of a physical asset or process. This virtual representation is more than just a model of the physical asset. Thanks to IoT sensors, the twin can receive continuous, real-time data from the asset. This unique one-to-one correspondence makes it possible to virtually monitor the object status, location and condition. Digital twins are vital for improving production processes, by allowing manufacturers to test future scenarios that can enhance asset performance and proactively anticipate maintenance faults. Digital twins are now being used to manage the performance, effectiveness, and quality of assets involved in manufacturing operations, such as machines, production lines and factories. When advanced visualization, IoT, and analytics are applied to these assets, manufacturers can take a more strategic and holistic approach to asset management. Digital Twins are the outcome of continuous improvement in the creation of product design and engineering activities.
