A meeting is an assembly or gathering at a prearranged time, usually to discuss specific topics and to exchange information about the specific topics. It is essential for an efficient group meeting to provide an organized representation of the meeting. A representation of ontology for the meeting will be an answer for the organized representation to support the meeting efficiently. Moreover the ontology can provide an inference scheme from the meeting concepts such as domains, sub-domains, classes, properties, and relationship of meetings. In this paper the strategy for the domain decomposition, the definition of features, and the ways in which features are shared by various operations and structure changes, are discussed. We conclude with a discussion of some of the issues raised by the project and the steps underway to address them.

A knowledge based design system(KBD) is required to implement a design environment which can satisfy the customer's requirements and re-use the designer's experiences and knowledge. However, if the KBD system could only represent the knowledge which can codify a rule-type, it would be considered an inadequate and limited knowledge based system. And a closed KBD system can not have the relationship with an external knowledge base. This paper will be focused on the implementation on an open KBD system associated with a distributed knowledge base. We propose an ontology knowledge map for an excavator design, an open KBD system, and a methodology for an association with an external knowledge base.

A layout design of an excavator front is a coupled design. Parameters of the layout design are coupled each other. So it is difficult to make decisions to set the parameters of the layout of an excavator front. We analyze the parameters of the layout design of an excavator front. We regroup the parameters as interface groups. And we suggest a new design process which is based on the interface groups. And we redesign user-interfaces of the Knowledge based Excavator Design System(KEDS).

STEP AP203 is a standard for exchange 3D CAD models. The second edition of AP203 is support to express the constructive solid geometry with construction history. However EXPRESS language is not support to express semantic relations. So it is hard to trace the design history. In this research, we suggest an expression of OWL(Web Ontology Language) based CAD models to trace the design history.
품질기능전개와 공리설계를 이용한 고객지향 굴삭기 프론트초기설계 시스템

A design needs various experience and design knowledge through a whole design process. Despite of all efforts and time, it is not easy to introduce a product that meets all customer"s needs and expectation in time. To achieve the product goal, designers need a set of sequential process to find appropriate design parameters and ensure customers" needs and requirements. In this research we propose a design methodology for the initial design of an excavator front group with existing QFD(Quality Function Deployment) and Axiomatic Design to satisfy customer"s requirements. It turns out that the proposed methodology can support designers more effectively, objectively, and systematically.
