Abstract

Any evaluation of a ship design process should take into account design phase costs, the time elapsed during the design phase, the production cost and ultimately ship performance in service. This paper reviews various aspects of ship design in the context of their effects on the cost items. The benefits of concurrent and cooperative engineering in basic ship design are discussed, and the use of a product model in solving problems is presented. The product model concept applied in NAPA (the Naval Architectural Package), known as the Ship Model, is described, and its advantages in concurrent ship design are demonstrated through examples. 1 Introduction Computers have been used in ship design for about 30 years, over which time the hardware has developed enormously. The development of sof
