Modeling and simulation in intelligent manufacturing

With the continuous deepening of the application of information technology in the manufacturing field, the informatization of manufacturing systems has developed from unit digital manufacturing to integrated networked manufacturing, and then to comprehensive digital, networked and intelligent manufacturing. As a comprehensive information technology integrating computer, model theory, and scientific computing, the modeling and simulation technology plays an irreplaceable role in the development process of manufacturing informatization and is widely applied in all stages of product life cycle containing design, production, testing, maintenance, procurement and sales. This paper reviews and summarizes the research and application of modeling and simulation technology in manufacturing, and analyzes typical simulation techniques in manufacturing from aspects of manufacturing unit simulation, manufacturing integrated simulation and manufacturing intelligent simulation.
