DESIGN OF PLANNING LEVEL SHIP PRODUCT MODEL FOR SHIP INITIAL DESIGN

Abstract

This paper introduces a design of planning level ship product model (called SPPM hereinafter) based on ISO 10303 Standard for The Exchange of Product Model data (STEP). For the design of this model, the information modeling methodologies such as Integration Definition (IDEF) methods and Unified Modeling Language (UML) were reviewed, and a hybrid method was established. By using this method, ship initial design process was analyzed, and STEP-based information model and class libraries for SPPM were defined. For the data structure of this model, the shipbuilding Application Protocols (AP215, AP216 and Ship Common Model) of STEP were investigated and utilized to facilitate sharing of product model data with other CAD systems of subsequent stages. For the implementation and the verification of the model, a prototype system was developed using the ACIS geometric modeling kernel and object-oriented database management system.
