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。

关键词: 本体, 创新方法, 工艺设计, 知识模型

Abstract: In order to further extend the knowledge of manufacturing planning innovative design, a knowledge model oriented towards process innovative design and relevant retrieval methods are proposed. Before the discussions of characteristics of process knowledge and its expression, this paper presented the goal-based knowledge constituents and the ontology-based logical structure for management, regarding knowledge features and the scope of it. A knowledge organization model of manufacturing planning design is established, in which the function ontology and flow ontology are constructed under the framework of "function+flow+case", and the ontological expression of functions such as abstract flow, workpiece characteristics, and manufacturing resources is achieved. Through the combination of innovative methods and methods of manufacturing planning cases, a goal-oriented knowledge semantic model of manufacturing planning design is proposed. Based on the appositive and hyponymy extension of ontological terms related to function and flow, a process knowledge retrieval model aiming for innovative design, along with a prototype system, are established by means of the extended algorithm, semantic retrieval, and word segmentation.

Key words: innovation approaches, knowledge model, manufacturing planning design, ontology
