【摘要】：在机械产品方案设计中涉及大量半结构化或者非结构化知识,现有的知识表示方式无法支撑设计知识的有效共享与重用,知识存储模式无法适应设计知识的复杂性特征。本文运用基于本体和NoSQL方法对机械产品方案设计知识和设计案例进行知识表示与存储,提出了基于FBS模型的机械产品方案设计本体构建方法,以及基于本体和NoSQL的机械产品方案设计存储模型。在此基础之上,以某机械产品为例,完成了本体构建和设计知识存储系统的构建,并与传统的关系型数据库的知识存储与查询系统进行了对比分析,实现了产品方案设计知识的语义化表示以及合理高效的存储,有效地支撑设计知识的共享与重用。
[Abstract]:A large amount of semi-structured or unstructured knowledge is involved in mechanical product scheme design, and the existing knowledge representation can not support the effective sharing and reuse of design knowledge. The knowledge storage pattern can not adapt to the complexity of design knowledge. This paper uses ontology and NoSQL method to express and store the knowledge of mechanical product scheme design and design case. In this paper, the method of constructing mechanical product scheme design ontology based on FBS model and the storage model of mechanical product scheme design based on ontology and NoSQL are put forward. On the basis of this, a mechanical product is taken as an example. The ontology construction and design knowledge storage system are completed, and compared with the traditional relational database knowledge storage and query system, the semantic representation of product design knowledge and reasonable and efficient storage are realized. Effectively support the sharing and reuse of design knowledge.
