From the construction of the hull, the precision of our management gap more evident. Shipbuilding precision management ( Precison Controls for Hull Construction ), introduced from abroad so far, currently in the domestic shipbuilding gets rapidder development and application. We study Japanese, Korean and other advanced shipbuilding countries that in shipbuilding technology to the rapid development, fundamental point is carried out the results of precision management. Shipbuiding precision management is most consistent with the lean shipbuilding thought, is the important characteristic of lean shipbuilding. Shipbuiding precision management is by using the method of mathematical statistics, through the process of shipbuilding production management and processing precision of welding heat deformation error control, use of compensation in lieu of allowance way, reduce shipbuilding processing, assembling and welding of the invalid labor. Japanese shipyards are generally designed for precision management organization, responsible for the organization and advance the shipbuiding precision management. Key words: precision management ; Lean Shipbuildi
