Execution Process Monitoring for Ship Curved Block Construction Based on Task Package and Workload Distribution Sheet

Aiming at the demands of top-down task transmission and bottom-up status coordination in the execution of ship curved block construction, a hierarchical execution process monitoring technique considering workplace, curved block, task package (TP) and workload distribution sheet (WDS) was put forward. Adopting linear fitting and graphics epitaxy, the plane vector projection modeling for ship curved block was achieved. Based on visualized monitoring technology for curved blocks evolution over time in workplace, a hierarchical execution process monitoring system was built. Through data collection and feedback based on work distribution sheet, the backwards status coordination was implemented. At last, the validity of the proposed technique was verified by an application example.
