The processes of the engineering design are generally held on from abstract objects to specific objects gradually. This stepwise process holds true with the design of merchant ships. And the product information is describes in two ways; one is the extensional way, the other is the intentional way. The concept of extensional description is practiced as configuration design and layout design. The concept of intentional description is practiced as parametric design.<br>On the other hand, authors already propose the top-down oriented design approach. In this approach, two concepts are proposed as an elementary factor of design information model;“information of entity”and“information of attribute”. Furthermore two information flows are proposed:“specification for model structure”and“specification for model status”. The specification for model structure means a structure of product model described by information models of entity and attribute. And a specification for model status means definitely description of information of relation and attribute values in the defined model and management that information. The extensional description of product model information is corresponded to specification for model structure, and the intentional description is corresponded to specification for model status". Thus top-down oriented design approach is applied to merchant ship design. The prototype system based on this concept is implemented, and some examples are shown.
