In order to improve the efficiency of ship segment construction, monitor and analyse the segment construction process, a Unity3D-based shipyard segment status kanban management system is proposed based on the current status of segment construction in the shipbuilding industry. The convenience of Unity3D-based kanban management function design is studied and the advantages of developing in the system interface are analysed. Combined with the application of actual production activities, feedback information is collected and improved, enabling effective monitoring and management of the segment manufacturing process, improving operational efficiency and achieving just-in-time production.
