Recently, an economic environment of industry changes for the worse in Japan. Therefore, a new strategy is necessary to get more competitive technology in design stage of ship. A new concept which is called ADDA (Advanced Design by Analysis) is now introduced. In order to realize "Advanced Design by Analysis", Computer Aided Engineering systems should be discussed from the standpoint of integrated system. In this paper, the following systems are integrated by using the concept of product definition system. 1) System for calculation trim, stability, and so on. 2) System for calculation of ship motions and wave pressure. 3) System for calculation of strength for ship structure. 4) System of short-term and long-term predictions for local stresses. In order to integrate those systems, some kinds of revision in product definition system which were implemented in SODAS were carried. And furthermore, new input and output generator for the respective CAE systems are made. The integrated system makes it possible to carry ADDA in a relatively short time. The actual processing time for a special ship was 20 hours. Therefore, designers who have to design a new ship are able to carry ADDA more than once by using this system.
