Driving Intelligent Manufacturing: An Application Study on Digital Twin in Factory Digitalization

With the rapid development of digital transformation, digital twin has got rising attention from both academia and industry. Based on new generation of information technology, digital twin has built an integration of virtual and real world with the ability of interconnection and intelligent inter-operation, which has narrowed the gap between physical and digital world, becoming an important enabler for intelligent manufacturing. The paper mainly discusses the application of digital twin in manufacturing scenarios, and its role in enterprises' digital transformation through intelligent operation and maintenance, virtual debugging, anomaly diagnosis, risk prediction, decision-making assistance, intelligent production scheduling and system optimization, so as to help improve production efficiency and promote digital economy. The paper aims to provide reference for the industry in planning and building a digital twin world, and help with the world's technological evolution and industrial development.
