文章立足于知识重用,提出了基于本体的知识库构建模型,并设计了一种新的实例检索流程和相似度算法。以某部件的设计为例,分析了该部件在设计过程中基于知识重用的实例检索方法,展示了此方法在产品设计过程中的实际应用。 Based on knowledge reuse, this paper proposes an ontology-based knowledge base construction model, and designs a new instance retrieval process and similarity algorithm. Taking the design of a part as an example, this paper analyzes the example retrieval method based on knowledge reuse of the part in the design process, and shows the practical application of this method in the product design process.
