Abstract:In view of the extensive manufacturing process management mode of steel box girder industry, based on lean production and industrial engineering theory, combined with the maturity level of production management of the enterprise, in accordance with the relevant requirements of modern steel structure intelligent manufacturing construction,, a steel box girder production and manufacturing execution system is established. The system develops production plan execution, product quality control functional modules such as equipment operation and maintenance management can effectively improve the level of refined production management and support the operation decision-making of steel box girder project by connecting things with important resource elements of the workshop through workshop industrial network and data acquisition terminal。
