Abstract

A gigantic ship is constructed by assembling various types of ship blocks, each block being made by cutting and piecing the steel-plates together. The steel-plate piling process as the initial stage of ship construction sorts and manages the steel-plates according to the ship blocks that the steel-plates are used to make. The steel-plate piling process poses some problems such as process delay due to piling errors, safety vulnerability due to the handling of extra heavy-weight objects, and the uncertainty of work plan due to lack of information management in the pile spaces. We constructed a steel-plate piling process system based on the context-aware computing to resolve such problems. We built simulation system that can simulate the piling process and then established a smart space within the system by using tags, sensors and a real-time location system in order to collect context information. Workers receive an appropriate or intelligent service from the system.

선박 건조공정의 초기 단계인 강재적치처리공정에서는 입수한 강재를 어느 선박블록을 제작하는데 사용될 것인가에 따라 수십 개의 적치장을 이용하여 분류한다. 이 과정에서 강재를 잘못된 적치장에 적치하는 적치 오류, 무거운 강재를 다루는데 수반되는 작업자 안전 취약성, 각 적치장의 강재 정보 관리의 미비로 인한 작업 계획의 불확실성 등으로 인하여 생산성이 크게 저하된다. 이러한 문제점을 해결하기 위하여 상황인식 컴퓨팅 기술을 적용하여 지능형 강재적치처리시스템을 구축하였다. 연구의 효율성을 위하여 강재적치처리 작업과정을 보여줄 수 있는 시뮬레이터를 제작하였으며, 센서, RFID 태그, 실시간 위치추적시스템과 같은 기술을 활용하여 공간 내에 있는 객체들의 위치 및 작업 처리 상태 등, 상황정보를 실시간으로 획득할 수 있도록 유비쿼터스 컴퓨팅 공간을 구축 하였다. 본 연구는 유비쿼터스 컴퓨팅 기술을 적용한 선박 건조 생산성 제고는 물론 대규모 생산현장에 IT를 적용하는 제조IT 융합연구의 새로운 모델을 제시하였다는데 의미가 크다고 할 수 있다.
