Abstract

장기간 수명주기(Life Cycle)을 갖는 도시철도차량은 초기 도입비용보다 유지보수비용이 많은 비중(60%~70%)을 점유하고 있으므로 효율적인 유지보수 연구를 통하여 유지보수 비용의 절감과 대형시스템의 수명연장을 추구하는 일이 무엇보다 시급하다. 이를 위해 신뢰성기반의 유지보수체계에 대해 여러 산업분야의 국내 외 사례 조사 분석을 통해 도시철도차량 신뢰도/가용도 관리시스템을 구성하였다. 본 연구에서는 이 시스템이 가져야 할 주요 기능을 상세히 정하고 성공적인 시스템 개발이 될 수 있도록 관련 시스템을 개발하였다. 본 논문은 성공적으로 개발이 완료된 도시철도차량 신뢰도/가용도 관리시스템에 관한 내용을 기술한 것이다. The maintenance of an urban transit vehicle accounts for 60-70% of total costs over its entire life cycle, so it is critical to reduce maintenance costs and extend the life times of urban transit EMUs (electric multiple units) through research. For these researches, the reliability and availability data management system was constructed through the case study of several industries in the domestic and international in the field of reliability centered maintenance system. And we created a system to manage reliability and availability data for use in urban-EMU maintenance. In this work, we identified the major functions needed to successfully develop the system. Here we report the successful development of a reliability and availability data management system for maintenance of urban transit vehicles.
