Abstract

In the process design and reuse of marine component products, there are a lot of heterogeneous models, causing the problem that the process knowledge and process design experience contained in them are difficult to express and reuse. Therefore, a process knowledge representation model for ship heterogeneous model is proposed in this paper. Firstly, the multi-element process knowledge graph is constructed, and the heterogeneous ship model is described in a unified way. Then, the multi-strategy ontology mapping method is applied, and the semantic expression between the process knowledge graph and the entity model is realized. Finally, by obtaining implicit semantics based on case-based reasoning and checking the similarity of the matching results, the case knowledge reuse is achieved, to achieve rapid design of the process. This method provides reliable technical support for the design of ship component assembly and welding process, greatly shortens the design cycle, and improves the working efficiency. In addition, taking the double-deck bottom segment of a ship as an example, the process knowledge map of the heterogeneous model is constructed to realize the rapid design of ship process, which shows that the method can effectively acquire the process knowledge in the design case and improve the efficiency and intelligence of knowledge reuse in the process design of the heterogeneous model of a ship.

摘要

在船用零部件产品的工艺设计与重用过程中，存在大量异构模型，导致其中蕴含的工艺知识和工艺设计经验难以表达与重用。因此，本文提出一种针对船舶异构模型的工艺知识表示模型。首先，构建多元素工艺知识图谱，以统一方式描述异构船舶模型。然后，应用多策略本体映射方法，实现工艺知识图谱与实体模型之间的语义表达。最后，通过基于案例推理获取隐含语义并检查匹配结果的相似度，实现案例知识重用，以实现工艺的快速设计。该方法为船舶零部件装配与焊接工艺设计提供了可靠的技术支持，大大缩短了设计周期，提高了工作效率。此外，以某船双层底分段为例，构建异构模型的工艺知识图谱以实现船舶工艺的快速设计，表明该方法能够有效获取设计案例中的工艺知识，提高船舶异构模型工艺设计中知识重用的效率和智能化程度。
