The invention provides a ship design change single whole process
data management method and
system, and the method comprises the steps: constructing a standard
database, and maintaining standard data; inputting
design data, purchase data, operation data, production data and
quality data; carrying out the calculation through the change
list issuing time, the tray plan distribution time and the tray standard manufacturing period, and carrying out the change
list material application judgment; carrying out
change order dispatching judgment through
change order material application judgment and a
change order stage; and through the original drawing
work package number, the original drawing
work package state and the original drawing
work package real
work time, single construction department change and waste return judgment are carried out. The
data management method runs through data specifications and association relationships of all links such as design, purchase, production, operation and quality, realizes
data entry and management in the whole process of a design change
list, ensures close
collaboration of the links such as design, purchase, production and quality in the change process, and significantly improves the
overall efficiency and
project management level of ship construction.
