DefinitionA digital twin (デジタルツイン) is a technique that copies the shape and state of real equipment or products into virtual space as data, creating a twin that behaves just like the real thing.
ExplanationBecause data from sensors on the real side keeps updating the twin's state, looking at the virtual space shows you how things stand in reality right now. Running simulations on the twin under different conditions lets you forecast when failures will occur and check whether an improvement works, without stopping or damaging the real equipment.
AnalogyIt is like moving furniture around a scale model of a room before deciding where it goes. The difference is that a digital twin's model keeps updating itself as the real room changes.
Memory hookTwin means one of a matched pair. Picture the name literally: the real object has a sibling living inside the digital world.
