基于业务本体的产品设计知识表示方法

Product design knowledge representation based on bussiness ontology

为积累存储并表示产品设计过程中的知识与经验,提出了业务本体的概念。利用业务本体将知识与产品设计流程紧密关联起来,真正实现知识来源于设计流程且服务于设计流程。为更好地支持设计知识的共享与重用,分别从静态和动态两个角度给出了基于业务本体的知识表示方法,该方法使知识的语义信息更加丰富,大大提高了知识检索效率。通过在某军用车辆知识管理系统中的应用,验证了该知识表示方法的可行性与有效性。

In order to accumulate,store and represent knowledge and experience in product design process,the concept of business ontology was put forward.Through close association between knowledge and product design process by business ontology,knowledge which originated from design process and served design process was realized.In order to support sharing and reuse of design knowledge,knowledge representation method based on business ontology was provided respectively from static and dynamic perspectives.The method enriched semantic information of knowledge and improved knowledge search efficiency.Finally the feasibility and effectiveness of the method were proved by example of military vehicle knowledge management system.
