造船CIM用プロダクトモデルと設計用GUIの試作

产品模型是计算机集成工业系统的基础。它必须具有广泛的能力，从产品的初始阶段，基本/详细/制造设计和运营，直到退役。它必须同时具有多样性和一致性，才能在产品的整个生命周期内使用。本文结合船舶初步结构设计，对产品模型进行了检验。船体结构具有较好的多样性，但不同船型的船体结构可能具有相同的拓扑结构。结构可以划分为底部、侧壳、甲板和油罐结构等单元。结构的变化将表现为元素结构的组合。至于结构设计，知识应该与元素结构相结合，因为它们在整个系统中具有特殊的作用。在本研究中，原型系统是在Design++知识库设计软件上开发的。该库中表达了单元结构，用户可以很容易地推导出它的实例，并通过设计散货船的船中结构来验证其概念的有效性。

Product model provides the foundation of the computer integrated industrial systems. It must have wide capability for stages of the product from inception,basic/detailed/manufacture design and operation through through decommission. It must have variety and consistency at once to be used in the whole life of the product.In this paper, product model has been examined in the light of the preliminary ship structural design. The structure of the ship has good variety, however, ship structures of various ships might be topologically same structure. And the structure may be partitioned into elements such as bottom, side shell, deck and tank structure. The structural variety will be expressed in terms of the combination of the element strucures.As for the structural design, hnowledge should be incorporated with the element structure since they have particular role in the whole system. In this study, the prototype system has been developed on the Design++knowledge based design software. Element structure has been experssed in the library, and users may derive its instantion very easily.Implementation work identifies its conceptural effectiveness by designing the midship structure of the bulk carrier.
