With the deep application of new generation information technology in industry

traditional product research and development mode has changed. This paper introduces the modeling and simulation

dynamically predicts and estimates complex product lifecycle business process by using digital clues and digital twin

to achieve the business closedloop mapping of digital space and physical space of the product planning and definition

simulation and analysis

verification and confirmation. At last

combined with the smart manufacturing framework of aviation industry

the application idea in the production lifecycle is given to enhance the digital and intelligent level of the production process.
