知識工程方法在船舶結構設計的應用

Knowledge Based Engineering Methods for Ship Structural Design

在船舶結構設計過程中，需要經常查詢與計算船體主要尺度與船體構件強度相關的數據，因此若能藉由知識工程方法的建立，除了協助使用者提高船舶設計工作效率與品質外，還可以透過設計過程不斷的累積知識，進一步運用於往後新船的研發製造，不僅可減少設計時間並且節省製造費用以改善船廠的生產效能之外，更可提升船舶的性能，增進船舶的安全。本研究的目標是將知識工程相關技術應用在船舶結構設計上，透過設計知識庫與規則推論系統的連絡，將Tribon中的船舶結構設計資訊與知識工程系統相互結合。以知識工程方法建立船舶的結構設計知識庫，建立一套具有彈性、擴充性與操作性的船舶結構設計資訊推論機制，分別建立知識工程系統的使用者介面、知識庫與推論引擎。在此知識工程系統由Tribon系統的船舶結構設計資訊，透過Tribon的Vitesse所建立的介面，建立針對規則推論系統所需的船舶結構設計資訊文件，並且針對船舶法規進行管理與建立。整合設計資訊針對船級法規的規定直接設計，避免設計過程中發生構件間的衝突與錯誤，減少重覆設計及重複建模的步驟，以協助使用者在進行船舶結構設計時能提高工作效率與產品品質。 In the ships structural design process, needs to inquire and the computation hull related data, if can therefore because of knowledge the project method to construct, besides assists the user to raise the hull design working efficiency and the quality, but may also penetrate the design process unceasing accumulation knowledge, will further utilize will be new in the future the ship the research and development manufacture, not only may reduce the design time, and will save the factory expense to improve the shipyard outside the production potency, may promote ships' performance, will promote ships' security. This research's goal is the knowledge engineering correlation technique application in the ships structural design, by designs the knowledge-base and rule deduction system's linking, unifies mutually the Tribon in ships structural design information and the knowledge engineering system. Establishes ships' structural design knowledge base by the knowledge engineering method, establishes a set to have elastic, the extendibility and the operational ships structural design information deduction mechanism, and establishes the knowledge engineering system's user interface, the knowledge library and the deduction engine separately. Receives the Tribon system's ships structural design information in this knowledge engineering system, and carries on the management and the establishment in view of the ships rules and regulations. The conformity design information in view of the classification of vessels laws' and regulations' stipulation direct design, avoids designing in the process to have conflict and the mistake between component's, reduces redundant design and the redundant modeling step, assists the user when carries on the ships structural design to be able to raise the working efficiency and the product quality.
