基于过程本体的设计过程表示研究

Research on design process representation based on process ontology

根据对设计过程重用的要求,针对本体的特点,提出采用过程本体知识表示方法对设计过程进行表示,并分析过程本体的定义及特点,在描述设计过程一般模型的基础上,一方面通过抽取设计过程的过程本体,描述各过程本体间的层级关系,构建基于过程本体的设计过程本体层次模型;另一方面通过统一设计过程的概念、属性及关系,构建基于过程本体的设计过程本体库,最后在飞机垂直尾翼的部件蒙皮的设计阶段进行了初步应用及验证。

Based on the demand of design process knowledge reuse, according to the characteristics of ontology knowledge repre- sentation, process ontology knowledge representation method is offered, the definition and the characteristics of the process ontolo- gy are analyzed. In the basis of description of the general model of the design process, constructs the design process ontology hier- archy model through extracting process ontology of the design process and describing hierarchy among the process ontologies. Fur- thermore,constructs the design process ontology database through unifying the concept, attribute and relationship of design process. Finally, a basic replication and verification are given on the skin of vertical tail in the design process.
