Ship segment positioning management method and system and segment construction performance management method

The invention provides a ship segment positioning management method and system and a segment construction performance management method. The ship segment positioning management method comprises the following steps: acquiring real-time position information of each ship segment; and acquiring boundary information of the predetermined site area. According to the real-time position information of each ship section, the position relation between each ship section and the preset site area is judged, and the occupancy state of the preset site area is determined. And according to the occupancy state of each site, analyzing and screening out a site area into which each ship segment can enter. And according to the boundary information of the screened site area and the real-time position information of the corresponding ship segment, determining a moving path of the ship segment, and moving the ship segment into the corresponding site area according to the moving path. The positioning management of the ship segments is
