The invention provides a shipbuilding method and
system based on digital twinning, a medium and a terminal. The method comprises the following steps of establishing a shipyard three-dimensional model, and performing analog
simulation and optimization on a shipbuilding
business process according to a production mode of a shipbuilding
assembly line based on the shipyard three-dimensional model to form a shipbuilding virtual
system; establishing a real ship building
physical system; establishing
the Internet-of-things in the shipbuilding
physical system; establishing a ship construction digital twinning
management system; through data fusion between a ship construction virtual
system and a
physical system, various services such as intelligent production scheduling, collaborative process planning, product
quality management, production process management and control, equipment health management, energy efficiency optimization analysis and the like are provided for ship construction; the method is used for solving the problems that in the actual ship
building process, part
machining and installation information is not clear,
resource allocation is not reasonable, and
equipment state information is not known, the ship building efficiency is improved, and the ship building cost is reduced.
