Abstract: To addresses three core issues existing in the Manufacturing Execution System （MES） of the resin production line of Tianjin Beacon Coatings Industry Development Co.,Ltd.,namely the lack of 3D visualization,low data collection and integration levels,and insufficient decision support,this paper proposes an optimization scheme based on the in-depth integration of Building Information Modeling （BIM） and MES. By constructing a high-precision BIM model,the digital mapping of process equipment and pipelines is realized;collision detection is used to optimize pipeline layout;and standardized data interface protocols are established to break down information barriers. The research shows that this scheme can significantly improve the efficiency of production anomaly response and the level of quality control,providing a reusable technical path for the intelligent upgrading of process industries.

Key words: MES system, BIM, production line optimization, data integration, collision detection
