Abstract: Against the backdrop of the continuous expansion of project scale and increasing complexity in railway technology enterprises, this paper designed a project material management system for them to address the common problems, such as extensive material management, weak process control, information silos between various systems, and lack of supplier collaboration. By adopting key technologies including warehouse visualization based on Geographic Information System (GIS), intelligent list recognition based on Optical Character Recognition (OCR), and real-time tracking of third-party logistics, the paper improved inventory transparency, material information collection efficiency, and supply chain responsiveness. The practical application results show that this system implements refined management and control throughout the entire project process, increases inventory turnover rate and business collaboration efficiency, and enhances enterprise operational efficiency and management level.
