초록

협업적 제품 설계 환경에서는 여러 설계자가 작업에 참여하기 때문에 설계자간의 원활한 의사 소통이 필수적인 요소이다. 즉, 제품 설계에 내재되어 있는 다른 설계자의 설계의도를 파악할 수 있어야 하고, 각 설계자마다 사용하고 있는 상이한 모델링 용어에 대한 의미적 처리가 필요하다. 시맨틱 웹에서 온톨로지는 의미 정보를 명시적으로 표현할 수 있기 때문에 데이터와 서비스에 대한 통합되고 일관된 접근을 가능하게 한다. 따라서 제품을 여러 설계자가 설계하는 협업적 환경에서 온톨로지를 사용한다면 조립체내의 내포된 공학적 관계들, 공간적 관계들, 그리고 접합 관계들이 명확하게 표현되고, 추론을 통해 설계자의 의도가 파악되어 설계자간의 의사소통이 원활하게 이루어질 수 있다. 본 논문에서 는 조립체를 온톨로지를 이용하여 표현함으로써 협업적 환경에서 조립체 설계정보를 공유할 수 있는 시맨틱 조립체 모델링 프레임워크를 제안한다. 시맨틱 조립체 모델링 프레임워크에서는 조립체 관계 모델(Assembly Relationship Model, ARM)을 OWL(Web Ontology Language)와 SWRL(Semantic Web Rule Language)로 표현한다. 이를 통해 조립체 내에 내포된 공학적 관계들, 공간적 관계들, 그리고 접합 관계들이 명확하게 표현되고, 추론되어 설계 의도가 파악된다.

In the collaborative product design environment, the communication between designers is important to capture design intents and to share a common view among the different but semantically similar terms. The Semantic Web supports integrated and uniform access to information sources and services as well as intelligent applications by the explicit representation of the semantics buried in ontology. Ontologies provide a source of shared and precisely defined terms that can be used to describe web resources and improve their accessibility to automated processes. Therefore, employing ontologies on assembly modeling makes assembly knowledge accurate and machine interpretable. In this paper, we propose a framework of semantic assembly modeling using ontologies to share design information. An assembly modeling ontology plays as a formal, explicit specification of a shared conceptualization of assembly design modeling. In this paper, implicit assembly constraints are explicitly represented using OWL (Web Ontology Language) and SWRL (Semantic Web Rule Language). The assembly ontology also captures design rationale including joint intent and spatial relationships.
