基于本体的汽车协同研发平台构建

为了有效组织管理汽车全生命周期领域内已有知识，把本体思想引入该领域的知识表示中，开发了基于本体的汽车协同研发平台。首先，建立了面向汽车全生命周期的领域本体构建模型，采用巴科斯范式对基于概念、关系、属性、规则和案例五要素的汽车领域本体进行统一的描述和表达；其次，把汽车全生命周期领域知识抽象为概念本体树，利用产品对象本体库、制造技术本体库和企业业务本体库组织和存储领域本体；最后，在本体知识库的基础上，开发基于本体的汽车协同研发系统。系统为汽车领域知识的检索、重用与共享提供了一个有效的平台。

Construction of Automobile Collaborative R & D Platform Based on Ontology

To effectively organize and manage knowledge oriented automobile lifecycle, ontological thought is introduced to represent knowledge, and an ontology-based automobile collaborative R ＆ D platform is developed. Firstly, the model of domain ontology construction for automobile lifecycle is established, and automobile domain ontology is described and expressed by BNF formulations, i.e. conceptions, relations, attributes, rules and cases. Secondly, domain knowledge of automobile lifecycle are abstracted as concepts ontology tree, and the domain Ontology is stored respectively in the product ontology base, the ontology base of mechanical technology and the ontology base of enterprise operation. Finally, an ontology-based automobile collaborative R ＆ D system is achieved based on the ontology knowledge base. This system provides an effective platform for automotive domain knowledge retrieval, reuse and sharing.
