In designing for ship production, the production method should be considered and it’s possible to reduce the manufacturing cost in designing procedure. A review of background of ship design that had minimized production costs, shows the principles and problems of these methods. Modern designing methods for manufacturing, considers hydrodynamic efficiency and less manufacturing cost. Quantifying the results of required designing changes in modern methods, is only possible with Bottom-Up method which is described in this paper. This method needs sufficient data and information of production process.
