선박 초기설계에 FBS 설계 모델의 응용에 관한 연구

Abstract

AbstractThe design process becomes more difficult due to the increasing complexity of products. Thus, without any proper design experience, designer cannot han dle his design problems systematically. Besides, the conventional optimal design method cannot be used effectively at the early design stage, since most design problems must be formulated in terms of objective and constraint functions based on the mathematical co ncepts of Operation Research. Thus, in this paper, new design concept based on FBS (Function-Behavior- Structure) design model is introduced to help the novice design er formulate the complex design problems systematically into a mathematical form. In thi s FBS model, function means the designer's new intents designer wants to create for, struct ure stand for a final product configuration and behaviour is a product's performance. FBS des ign model is thus rather totally different concept used for formulating design problem, compared with conventional optimal design method. To validate this new FBS model, 330K VLCC design case is performed, and we found, though it is one design example case, that this new design concept could be effectively used for future ship design proble ms since, during the formulating design problem, the only engineering terminology su ch as function, structure, and behaviour of design product is used based on the engineerin g concepts, instead of mathematical terminology such as objective and constraints.※Keywords: Preliminary ship design(선박 초기 설계), Function(기능), Beh avior(행위), Structure(구조), Design activity(설계 행위)
