Abstract

FTMS, TCS, ITS equipment such as high-pass highway are just a situation that does not lack traceability and passive surveillance is related to fault DB has so far consisted of an integrated operations management to maximize utilization of the facility. In addition, there is no replacement parts are replaced when a failure occurs, increasing the number of parts and repair time I have trouble growing, and becoming a service interruption whenever you replace each time. In this study, proactively manage the failure history of a highway facility ITS tries to preventive maintenance. Therefore, the error history is based on the reliability of the high-pass facilities theory to calculate the reliability of the system through a systematic statistical analysis Operational Availability. The fault number and the time the replacement period through the estimate decreases and can reduce the budget expenses by securing the spare parts quantity, establish a management plan in part by improving the quality of the system through constant preventive maintenance, quality of service at all times It may direct the non-stop operation state of the available state.

현재 FTMS(Freeway Traffic Management System: 고속도로 교통관리 시스템), TCS(Toll Collection System: 요금 징수 시스템), 하이패스(Hi-Pass: 통행료 전자 지불 시스템)등의 고속도로 ITS(Intelligent Transportation System) 설비들은 단순한 이력관리 및 수동적인 사후관리가 이루어져 고장관련 DB가 부족하여 시설물의 통합운영관리 활용을 최대화 하지 못하고 있다. 또한, 부품의 교체시기가 없어 고장 발생 시마다 부품을 교체하다 보니 고장건수 증가 및 수리시간이 증가하며, 매번 교체 할 때마다 서비스가 중단되는 문제 점이 발생한다. 본 연구에서는 고속도로 ITS 시설물의 고장이력을 사전에 관리하여 예방적 유지관리를 하려한다. 따라서 하이패스 시설물의 고장이력을 신뢰성 이론에 기반을 두고 체계적인 통계분석을 통해 시스템의 신뢰도인 운용가용도를 산출한다. 교체시기 산정을 통해 고장건수 및 시간이 감소하며 예비품 수량을 확보하여 예산 비용을 줄일 수 있고, 부품의 관리계획을 수립하여 지속적인 예방적 유지관리를 통해 시스템의 품질을 향상시키고, 서비스 품질을 항시 가용한 상태인 무 중단 운용상태를 지향 할 수 있도록 하는 것이 본 연구의 목적이다.
