COMPUTERIZED MAINTENANCE INFORMATION SYSTEM FOR URBAN TRANSIT

초록

In the 21st century, the informationization on various fields is progressed quickly and leads to the new frontierless market transcending the limits of time and space. In the urban transit, the computerized systems for development of new product, operation, maintenance, repair manual, document, management, etc. have not yet established systematically. They are partially computerized. The decentralized management of these various informations decreases the maintenance efficiency and increases the maintenance cost as well. And also it cannot support the rapid repair of breakdown and the preventive-maintenance which is helpful in the safety operation of urban transit. In this paper, we introduce urban transit maintenace information system based on web which is developed by KRRI. This maintenance information system is now being operated by two metro corporations in Korea, i.e. Seoul METRO and SMRT since June 2005 and will be expected to be applied to other metro corporations. We’re sure that this system could reduce the maitainence cost and improve the operating safety of urban transit.
