Abstract:

To solve the problems of the design knowledge sharing and reuse difficulty in the process of collaborative product design, an ontology-based knowledge modeling method of collaborative product design for multi-design teams was proposed. A collaborative product design work model for multi-design teams was established by analyzing the characteristics of collaborative product design firstly, and an ontology construction framework for collaborative product design was also put forward. At the research background of mechanical product collaborative design, the knowledge modeling process of collaborative product design for multi-design teams based on ontology modeling theory was studied by utilizing the classification and description method of thinking, including the design knowledge classification and concepts extraction, the OWL description and the property definition. On this basis, a knowledge ontology model for mechanical product collaborative design was constructed. Finally, an application case was presented to illustrate the feasibility and validity of the knowledge modeling method.

摘要：

为解决多设计团队协同产品设计过程中设计知识共享和重用困难等问题,提出了一种基于本体的多设计团队协同产品设计知识建模方法。分析了多设计团队协同产品设计的特点,建立了多设计团队协同产品设计工作模型,提出了多设计团队协同产品设计知识本体构建框架。以本体建模理论为依据,以机械产品协同设计为研究背景,利用分类和描述的思想方法对基于本体的多设计团队协同产品设计知识建模过程进行了研究,包括设计知识的分类与概念抽取、设计知识的OWL描述以及属性定义。在此基础上,构建了机械产品协同设计知识本体模型。最后通过应用实例验证了该方法的可行性和有效性。
