Abstract

As flexible manufacturing systems (FMSs) are highly automated and required flexibility to satisfy market need, dispatching rules are constrained by specific environments of manufacturing systems such as mechanical failures, absence of employees, and lack of spare parts. In this paper, an ontology-based knowledge approach is proposed to improve efficiency of system through adapting suitable dispatching rules, considering context in a FMS shop floor, which consists multiple manufacturing cells. the multi-agents monitor manufacturing system status and job so that it figures out a dispatching rule considering context. To demonstrate the proposed approach, a proof-of-concept prototype system has been implemented in the $JADE^{TM}$ platform and Protege to make OWL DL ontology.

유연생산시스템은 고자동화 생산시스템일 뿐만 아니라, 사용자와 시장의 요구를 만족시키기 위해 유연한 생산시스템이 요구됨에 따라 작업배정규칙 할당에 있어서 시스템과 작업환경에 많은 제약을 받게 된다. 본 논문에서는 온톨로지 지식 기반의 작업환경을 고려한 유연생산시스템의 작업배경규칙 할당방법을 제시한다. 에이전트를 이용하여 작업장 환경과 작업내용을 모니터링하고, 이에 적합한 작업배정규칙을 온톨로지 지식으로부터 추론하여 시스템에 적용한다. 본 시스템 개발을 위해 멀티에이전트를 지원하는 $JADE^{TM}$ 플랫폼을 이용하였으며, 온톨로지는 Protege를 이용하여 개발되었다.
