【摘要】：在工艺设计领域,为扩展创新设计知识空间,提出面向创新设计的工艺设计知识模型及检索方法。在讨论工艺知识特征及知识表达方法的前提下,针对工艺知识特点及领域范围,提出基于目标的工艺设计知识构成要素、基于本体的工艺知识管理逻辑架构,建立工艺设计知识组织模型,以"功能+流+案例"为规则构建作用本体及流本体,并完成对抽象流、工件特征以及制造资源等功能的本体化表达。通过结合创新方法与工艺案例的方法,提出面向目标的工艺设计知识语义模型。基于对功能和流相关本体词汇同位及上下位扩展的研究,利用扩展算法、知识语义检索、分词模型等方法提出可满足创新设计目标的工艺知识检索模型,并建立了原型系统。
[Abstract]:In the field of process planning, in order to expand the knowledge space of innovative design, a process planning knowledge model and retrieval method for innovative design are proposed. On the premise of discussing the characteristics and expression methods of process knowledge, aiming at the characteristics and domain scope of process knowledge, this paper puts forward the constituent elements of process planning knowledge based on goal and the logical framework of process knowledge management based on ontology. The process planning knowledge organization model is established, and the function ontology and the flow ontology are constructed according to the rules of "function flow case", and the ontological representation of abstract flow, job feature and manufacturing resources is completed. By combining the innovation method with the process case method, the goal oriented process design knowledge semantic model is put forward. Based on the research of functional and flow-related ontology lexical homology and upper-lower extension, a process knowledge retrieval model, which can meet the objectives of innovative design, is proposed by means of extended algorithm, knowledge semantic retrieval and word segmentation model, and a prototype system is established.
