Digital twins as the name applies are an exact replica of something in our physical world. It is a data-driven representations of physical systems using IoT sensors and analytics. Digital twins provide engineers the virtual tools for managing assets and resources while improving performance.
Digital twins combine real-time simulation of system dynamics and a set of executive controls. Companies develop digital twins by attaching sensors to their products and equipment in order to monitor systems and model system dynamics. In one example, a digital twin of an aircraft’s engine enables pilots to monitor the health of an engine in real time.
Digital twins can manage facilities, machines, systems, factories, etc. Companies like Siemens and the General Electric have built digital twins of jet engine components that predict their remaining life and the optimum maintenance intervals.
