Abstract

Seoul Metropolitan Rapid Transit Corporation, managing the line number 5,6,7 and 8 has inspected and maintained for the maintenance of the facilities spread in the extended 152km and 148 stations. Despite the thorough inspection for prevention of the facility failure, the failure has continuously occurred, due to the environmental factors of the underground, mechanical worn-out caused by frequent use, aging facilities, system error, negligence on use, etc. We have achieved a 53.4% reduction in the number of failure by the end of June, 2010 by breaking the conventional way of inspections and maintenance and by adopting quantitative goal management and new way of work. In this paper, we will analyze the problems of inspections and maintenance of the railway facilities, the failure reduction strategy and the performance of each strategy.

서울지하철 5,6,7,8호선을 운영하는 서울도시철도공사는 연장 152km, 148개 역사에 분산되어 있는 시설물에 대하여 점검과 유지보수를 하고 있다. 장애예방을 위한 철저한 점검에도 불구하고 지하역사의 환경적인 요인, 빈번한 사용으로 인한 기계적인 마모, 시설물 노후화, 시스템 에러, 이용 상의 부주의 등으로 장애가 지속적으로 발생하고 있다. 서울도시철도공사에서는 지금까지 관행적으로 수행해 오던 시설물 점검방법과 유지보수의 틀을 깨고 정량적인 목표관리와 일하는 방식 변화 등을 통해 2010년 6월말까지 장애를 연간 53.4% 감소시켰다. 본 논문에서는 기존 도시철도 시설물 점검 및 유지보수의 문제점을 분석하고, 이를 개선하기 위해 추진했던 장애감소 전략과 각각의 추진성과를 분석한다.
