A digital twin is a digital representation of a product or process that is built using real-time sensor data and algorithms. It can be used in product design, simulation, monitoring, optimization, and servicing. Digital twin can virtually predict everything that will happen in the physical world, thus providing valuable insights for future planning and development. This also allows testing and better understanding of product in early-stage, thus minimizing downtime and reducing cost. Digital twin technology is the future of designing and manufacturing a product, process or service.
