基于过程本体的设计过程表示研究

摘要

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 .%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。
