재구성 가능한 생산 시스템은 4차 산업혁명과 관련된 제조 개념으로 다양한 고객의 요구를 저렴하고 유연하게 충족시킬 수 있다. 기존 생산 시스템은 생산 라인에 포함된 설비와 인터페이스를 오픈하지 않아 생산 라인을 재구성할 때 기존 설비를 재활용하기 어렵다. 이러한 문제를 해결하기 위해 본 논문에서는 산업용 사물인터넷 아키텍처와 데이터 모델을 기반으로 재구성 가능한 제조 기술을 제안한다. 데이터 모델은 ISA-95 분류체계를 기반으로 하였으며, 재구성에 필요한 필드를 추가로 구성하여 데이터 모델을 설계하였으며, 재구성 아키텍처는 기존 설비를 계속 활용할 수 있는 방식으로 설계 및 구현하였다. 데이터 모델과 아키텍처는 데이터 모델 기반 설비 자동 검색 기능과 산업용 IoT 기반 데이터 실시간 전송을 통해 설치자가 설비의 설정값을 직접 확인해야 하는 문제를 해결했다. 마지막으로 재구성 제조 기술에 대한 데이터 모델을 통해 리드 타임을 21.62% 단축하였다.
